General information LESER Pilot Operated Safety Valve (POSV) LESER Pilot Operated Safety Valves (POSVs) are designed according to the API 26 standard. The full range of sizes from 1" x 2" up to 8" x 10" (DN 2 DN 200) with all orifices from D T is available for pressure ratings up to pressure class 200 x 600 1). Beyond API 26, LESER offers so-called Extra Orifices (also known as Full Port or Full Bore nozzles, see page 1). The Extra Orifices provide maximum capacity in relation to valve size. In addition, LESER POSVs come in two different functional designs, i.e. Pop Action (Series 810) and Modulate Action (Series 820). These designs determine the POSVs operating characteristics. Depending on their design, LESER POSVs open rapidly (Series 810 Pop Action) or gradually in proportion to system pressure (Series 820 Modulate Action). Details are shown on page 28. POSV-Main Valve and Pilot Valve Series 810 Series 810 Pop Action LESER POSVs Series 810 with rapid opening (Pop Action) are used for applications where the certified discharge capacity needs to be reached quickly are used for gas applications only have an adjustable blowdown of % of set pressure conforming to ASME VIII which can be adjusted beyond API standard up to 1% Series 820 Modulate Action LESER POSVs Series 820 with proportional opening (Modulate Action) Series 810 Pop Action Pilot are used to minimize medium loss are used if medium must not discharge to atmosphere open in proportion to the overpressure to ensure that only as much mass flow is discharged from the safety valve as is necessary to prevent further pressure increase Series 820 Modulate Action Pilot 1) Pressure ratings PN 400 / Class 200 in preparation 4

Good Reasons for the LESER Pilot Operated Safety Valve Pilot operated safety valves have been a proven technology for many decades especially in ASME oriented regions. However, some of the older designs show potential for improvement in areas like external tubing, capacity and delivery times. Based on customer feed - back and extended research and using Computational Fluid Dynamics (CFD), Rapid Prototyping and one of the most modern factories for safety valves, LESER has developed the latest POSV on the market. The new LESER POSV offers unique benefits for both users and assemblers /maintenance personnel that are listed below. Design Feature Benefit for user Benefit for assembler / maintenance Tubing between pilot valve and main valve integrated into top plate Less risk of damage to tubing Resistant against vibration No freezing Less tubing for easy removal of top plate Tubing between inlet and pilot remains accessible for easy cleaning Backflow preventer integrated into manifold block as a standard component Easy ordering, no extra cost Less risk of damage to backflow preventer No need for machining to retrofit backflow preventer Integral cast support brackets Compensation of reactive forces (high pressures) Easy handling during installation Pilot valve manufactured completely from stainless steel Less corrosion for higher operation reliability NACE conversion only requires exchange of spring All medium-wetted parts in tubing and pilot valve are either stainless steel or nickel-coated Corrosion resistance 6

Applications Functional areas Across applications, there are four main functional requirements covered by the LESER Pilot Operated Safety Valve (POSV). High Back Pressure Applications LESER POSVs can be operated in applications with a back pressure ratio (i.e. a ratio of back pressure / set pressure) of up to 0%. Spring loaded safety valves can be typically used up to 0% of back pressure. The absolute maximum back pressure is determined by the pressure class of the main valve outlet. Typically, LESER POSVs can be used for much higher back pressures than spring loaded safety valves. Applications Requiring Set Pressure Independence of Back Pressure The LESER POSVs open and operate independently of back pressure (within back pressure operating limits, see previous). The set pressure of the POSV is not affected by back pressure of any kind, i.e. superimposed, constant or variable. Applications with High Inlet Pressure Losses (above %) In these applications, POSVs with remote sensing should be utilized (refer to API 20 Part 2). Applications with Increased Tightness Requirements Since closing forces increase when approaching set pressure, LESER POSVs are particularly suitable for applications with high tightness requirements. Tightness is ensured up to 9% of set pressure because the closing forces increase approaching set pressure. Together with the defined blowdown, this allows operating the sytem close to the set pressure of the valve. In a POSV, the system pressure acts on the main valve piston trying to push it open. It is, however, opposed by the same pressure because system pressure is also re-directed to the dome area above the piston. Since the area of the piston exposed to pressure is larger in the dome than on the system side, this creates a greater net closing force on the main valve disc / nozzle. Approaching set pressure, closing forces increase. Comparison see page 10. 8

Applications Examples Because of their suitability for high back pressure and high tightness applications, LESER Pilot Operated Safety Valves (POSVs) are used in a number of industrial areas including the following: Compressors in Gas Main Systems Pressure relief devices in these applications must allow for high operating pressures in relation to set pressure, which are required for efficient gas transport. Additionally, compressor vibrations put through requirements on the tightness of the safety valve. LESER Series 810 and 820 POSVs offer an ideal solution for these conditions because: they enable highest possible operating pressure to set pressure ratios facilitating maximum energy density of transport medium they are not susceptible to leakage caused by compressor vibration as are spring loaded safety valves Downstream Oil and Gas Industry Long pipings to the flare systems and common blowdown are frequently used in refineries. Both conditions lead to high back pressure of 0% of set pressure or more. LESER Series 810 and 820 POSVs are used in these applications because: they offer high back pressure to set pressure ratios they operate reliably independent of back pressure Upstream Oil and Gas Industry Offshore platforms have especially high tightness requirements to avoid leakage. Furthermore, the weight and size of the safety valves should be minimized due to space limitations on the platform. LESER Series 810 and 820 POSVs are ideal for the up - stream oil and gas industry because of: their high tightness up to set pressure their bonnetless design which allows lower weight and lower valve height Pumps in All Industries Systems with positive displacement pumps are protected by safety valves. The medium is often discharged to the suction side of the pump which creates back pressure. LESER Series 810 and 820 POSVs are used because: they operate independently of back pressure they allow high back pressure to set pressure ratios 9

Operating Concepts in Comparison Based on the operating concept, the LESER product range can be broadly divided into: Spring loaded safety valves (Series 26, 441, 49) Safety valves with added control capabilities (Series 00, 810, 820) Since control improves efficiency, LESER has named the products providing added control the High Efficiency group. The High Efficiency group includes: Pilot Operated Safety Valves (POSVs) Supplementary Loading System (SLS) The following table summarizes the different operating concepts across the LESER product range. LESER High Efficiency product group Other LESER product groups Products LESER POSV (Series 810, 820) Pilot Operated Safety Valve LESER SLS (Series 00) Supplemetary Loading System LESER SLSV (Series 26, 441, 49) Spring Loaded Safety Valves Operating concepts In the POSV, a pilot valve actuates the main valve based on the pressure sensed at the inlet.

It is, however, opposed by the same pressure because system pressure is also re-directed to the dome area above the piston. Since the area of the piston exposed to pressure is larger in the dome than on the system side, this creates a greater net closing force on the main valve disc / nozzle. Approaching set pressure, closing forces increase. The SLS uses external compressed air and an actuator to apply constant pressure on the main valve in addition to the spring force. This ensures seat tightness up to set pressure. Without supplementary loading, the safety valve works like a standard spring loaded safety valve. When system pressure approaches set pressure, the net closing force of the disc / nozzle decreases. At set pressure, the closing force is equal to the opening force created by system pressure. These safety valve products differ in their design and functional characteristics. They each have their specific benefits and applications. 10

Seat Designs: API Standard Orifices and Extra Orifices The main valve of the LESER POSV Series 810 and 820 comes in a variety of orifices. These orifices are obtained by varying the diameter of the main valve nozzle (see illustrations below). For each nominal valve size, LESER offers several orifices which are in accordance with the API orifice system. These are termed API Standard Orifices. In addition, for each nominal valve size a full bore nozzle is also available where the orifice is beyond the API orifice system. LESER refers to this orifice as an Extra Orifice. With an Extra Orifice, the customer often has the choice to use a smaller valve size for a required orifice and capacity (for details see page 82). In the POSV, nominal valve sizes correspond to standard API and Extra Orifices as shown in the following table. Extra Orifice letters followed by a plus (+) sign, e.g. K+, mean that these valves offer a minimum of 2% more capacity than specified in API 26. For capacity values for Standard and Extra Orifices see the capacity tables on page 82.

Full bore safety valves meet the API 26 except for their orifice, so their orifice is identified by a Extra Orifice letter. API Standard Orifice Extra Orifice 1

Application range of soft seal disc and metal to metal disc at ambient temperature Different sealing designs are used for different pressure ranges to ensure maximum tightness. Generally, at lower pressures, soft sealings are used, at higher pressures metal-to-metal sealings are used. The following chart shows which sealing is used as a standard.

Components POSV Main valve, pilot valve, tubing and manifold block The LESER Pilot Operated Safety Valve (POSV) consists of four main components in its standard configuration: the main valve, which serves to protect the pressurized equipment the pilot valve, which controls the opening and closing of the main valve the tubing is identical for both POSV Series, i.e. 810 and 820 the manifold block with integrated backflow preventer (standard feature) Pilot valve Manifold block Tubing Main valve Backflow Preventer Included in standard configuration The backflow preventer prevents an unwanted opening of the main valve, which would cause backflow of medium from the outlet into the protected system. This problem can occur when there is back pressure that exceeds the inlet pressure (or insufficient pressure at the inlet), resulting in a net force acting on the valve piston in the opening direction, such as e.g. in a process running under vacuum. 18

Operating Cycle LESER Pilot Operated Safety Valve (POSV) is controlled by process medium. To achieve this, the system pressure is applied to the pilot valve (= control component for the main valve) via the pressure pickup. The pilot valve then uses the dome above the main valve piston to control the opening and closing of the main valve. 1. Below set pressure: normal operation During normal operation, the system pressure is picked up at the main valve inlet and routed to the dome. Since the dome area is larger than the area of the main valve seat, the closing force is greater than the opening force. This keeps the main valve tightly closed. While there are specific differences between the Series 810 Pop Action POSV and the Series 820 Modulate Action POSV, the basic operation of a LESER POSV can be described as follows. During operation, the POSV goes through these basic operating states: Operating states of the POSV 1. 2. At set pressure: actuating state At set pressure, the pilot valve actuates. The medium is no longer routed to the dome. This prevents a further rise in dome pressure. Also, the dome is vented. As a result, the closing force ceases as a pre-condition for the system overpressure to push the main valve open. 2.. Main valve opening The main valve opens. Depending on the design of the pilot valve, this opening is either rapid and complete (Pop Action) or gradual and partial following system pressure (Modulate Action).. 4. At closing pressure: refilling the dome If system pressure drops to closing pressure, the pilot valve actuates and again routes the medium to the dome. The pressure in the dome builds up and the main valve recloses either rapid and complete (Pop Action) or gradual and partial following system pressure (Modulate Action). 4. 19

Series 810 Pop Action Features The Series 810 Pop Action Pilot Operated Safety Valve (POSV) is characterized by rapid opening, or pop action. When set pressure is reached, the dome of the main valve is vented quickly and completely and the main valve opens just as quickly and completely. The medium from the dome is discharged to atmosphere. The Pop Action POSV is used mainly for gas applications. Product Features Robust and insensitive to vibrations. The robust connection of the pilot valve (= control valve for the main valve) to the main valve and the reduced exposed piping guarantee safe operation even if there are vibrations in the system. Easy spring replacement. The spring is easily accessible. This allows simple replacement of the spring, saving time and costs. In order to replace the spring only the top section of the bonnet needs to be removed. Other functional parts or soft goods do not have to be disassembled and therefore do not need to be replaced. Easy blowdown setting within the requirements of codes and standards. LESER sets the blowdown in the range of %, which conforms to codes and standards. This setting can easily be adjusted. Other testing devices are not required. A large pressure range of 2. 426 bar (6 610 psig) ensures that the Series 810 Pop Action POSV can be used for a wide variety of applications.

Series 810 Pop Action Operating Cycle 1. Below set pressure: normal operation feeding seat open, exhaust seat closed When the main valve is closed the Pop Action Pilot is in a static state. During the filling process and with opened filling seat the medium is channeled via the manifold block into the dome of the main valve. In normal operational state medium does not flow. The closing force of the spring acts on the relief seat and is bigger than the acting medium opening force. Operating states Series 810 1 2. At set pressure: feeding seat opening, exhaust seat closing When set pressure is reached, the pilot valve opens the exhaust seat and closes the feeding seat. This releases the dome pressure. The release of dome pressure is a pre-condition for the opening of the main valve by system pressure. 2. At and above set pressure (+ max. 1%): pop opening At set pressure, the main valve opens abruptly and completely feeding seat closed, exhaust seat open (Pop Action) (see bottom chart). The medium is channeled from the dome to atmosphere (see illustration on right). 4. At closing pressure: feeding seat open, exhaust seat closed When the system pressure drops to closing pressure, the pilot valve actuates and again channels the system pressure to the dome of the main valve. Here, the system pressure builds up, the main valve recloses. The closing stage (blowdown) can be adjusted from at least % (when pressure loss at the inlet is low) to max. 1% blowdown difference. 4 Opening Characteristic with Overpressure and Blowdown Difference: Series 810 Pop Action Lift 4 1 Below set pressure: normal operation 2 At set pressure Pop opening 4 At closing pressure blowdown 1 2 Set pressure Pressure 21

Series 820 Modulate Action Features The pilot valve in the Series 820 Modulate Action Pilot Operated Safety Valve (POSV) does not open the main valve abruptly after reaching set pressure (pop action), but in modulating to the system overpressure (modulate action). Above set pressure, only as much mass flow is discharged as is needed to prevent a further pressure increase. This avoids an unnecessary loss of medium. The LESER Modulate Action POSV is suitable for liquid as well as for steam and gas applications. Product Features The LESER Series 820 Modulate Action POSV has the same design related benefits as the Series 810 Pop Action POSV. It is robust, spare replacement is uncomplicated and it has a large pressure range of 2. 426 bar (6 610 psig). Furthermore, it offers the following specific benefits: Suitability for media that are harmful to health / environment. The Series 820 Modulate Action POSV releases the medium from the dome into the main valve outlet and not into the atmosphere like the Pop Action POSV. Since back pressure can occur here, the Modulate Action pilot valve has a back pressure compensating design. Same performance, full lift. The LESER Series 820 Modulate Action POSV has the same discharge capacity and the same lift when completely open as the Series 810 Pop Action POSV. Series 820 Modulate Action Pilot Valve (Diaphragm design) 22

Series 820 Modulate Action: Diaphragm or Piston design Depending on the set pressure, Series 820 Modulate Action Pilot Operated Safety Valves (POSVs) are equipped with a diaphragm for set pressures of 2. 0 bar (6 4 psig) a piston for set pressures of 0.01 426 bar (> 4 610 psig) The pilot valve uses the same springs in both designs. 2. 0 bar (6 4 psig) Diaphragm In the lower pressure range a frictionless diaphragm in the pilot valve accurately transmits system pressure. Approaching set pressure, system pressure builds up underneath the diaphragm. This upward force is opposed by the greater force of the spring pushing downwards. The spring force can be adjusted within the designated pressure range using an adjustment screw. On reaching set pressure, the diaphragm triggers the opening mechanism in the pilot valve. The diaphragm lift is restricted to 1. mm by design to protect against tearing. 0.01 426 bar (> 4 610 psig) Piston In the range of 0.01 426 bar (> 4 610 psig) a piston is used to transmit the system pressure to the pilot valve and to trigger the main valve's opening when set pressure is reached. Depending on the diaphragm or piston designs, specific parts and dimensions (e.g. the mounting of the diaphragm or piston dimensions) in the pilot may differ. Materials see page 0.

Series 820 Modulate Action Operating Cycle The operating cycles of the Series 820 Modulate Action and the Series 810 Pop Action POSV differ at two points: shortly before set pressure is reached and after reaching set pressure. At this second point actual modulation takes place in the Series 820 Modulate Action POSV. Modulation means that above set pressure 1. Below set pressure: normal operation feeding seat open, exhaust seat closed The system pressure is routed to the dome, keeping the main valve tightly closed (see illustration). the pilot valve will open the main valve in proportion to overpressure. Thus, there may only be a partial lift of the main valve. This ensures that only as much medium is discharged as is required for pressure reduction. Any unnecessary medium loss is avoided. Operating states Series 820 1 1a. Near set pressure: feeding seat closed, exhaust seat closed (not shown) Shortly before set pressure is reached, the pilot valve closes the dome feeding seat. This keeps the dome pressure stable. A stable dome volume is the pre-condition which allows the rising system pressure to push the main valve open at set pressure. 2. At set pressure (+ max. 1%): feeding seat closed, exhaust seat open With a further slight pressure increase, set pressure is reached and the pilot valve opens the dome exhaust seat. The dome volume is discharged and the main valve starts to open. 2 Opening Characteristic with Overpressure and Blowdown Difference: Series 820 Modulate Action vs. Spring Loaded Safety Valve Lift 4 Blowdown % % LESER springloaded safety valve for comparison only Pilot-operated safety valve Series 820 1 Below set pressure: normal operation 2 At set pressure Modulate opening 4 At closing pressure blowdown 1 2 9% 98% Set pressure 100% 110% Pressure 24

Series 820 Modulate Action Operating Cycle. Modulate opening: feeding seat closed or open, exhaust seat closed or open At this point, modulation takes place. This means that if overpressure remains within the modulating range of 9 110% of set pressure, the pilot valve will again close the exhaust seat. This stops discharge from the dome and keeps the main valve piston unchanged at the achieved lift. The achieved lift will always be enough to ensure pressure reduction, but not more than is required. During blow-off this intermediate state with a stable dome volume and main valve lift can occur repeatedly and at different pressure levels. To change the lift, there can also be partial opening movements with the exhaust seat opened, or closing movements with the feeding seat opened. Modulation ensures that only as much medium is discharged as is necessary to prevent the overpressure from exceeding the modulating range (see chart page 24). 4. At closing pressure: full closing feeding seat open, exhaust seat closed When system pressure drops below the modulating range to reach blowdown pressure, the pilot returns to its first state (with feeding seat open and exhaust seat closed). The main valve closes completely. 4 2

Screw Dimensions acc. to DIN EN 1092-1 The flange thickness of the inlet and outlet flanges of the Pilot Operated Safety Valve (POSV) may differ from the standard. Therefore stud-bolts for the flange connections may also be longer than stated in DIN EN 1092-1. To simplify the calculation of the correct bolt length, the quantity and sizes of the stud-bolts and nuts for the inlet and outlet flange connections are given below.

Screw Dimensions acc. to ASME B16. The flange thickness of the inlet and outlet flanges of the Pilot Operated Safety Valve (POSV) may differ from the standard. Therefore stud-bolts for the flange connections may also be longer than stated in ASME B16.. To simplify the calculation of the correct bolt length, the quantity and sizes of the stud-bolts and nuts for the inlet and outlet flange connections are given below. The listed screw dimensions are rounded to standard dimensions. The connection flanges are based on the ASME B16. standard.

Accessories For both series of the LESER Pilot Operated Safety Valve (POSV) the following accessories are available. The accessories allow the adaptation of your safety valve to various special operating conditions. Overview Maximum configuration Manual blowdown Option code R24 Option code R2 * Backflow preventer (standard feature) 4 Remote sensing Option code R28 2 Pilot supply filter Option code R0 1 Field test connector Option code R26 0

Accessories The available accessories for Series 810 and 820 provide solutions for the following special operating conditions: 1 Field Test Connector Option code R26 Operating condition: The pilot setting shall be tested without system shutdown and without increasing the system pressure. Solution provided: A field test connector is recommended when set pressure shall be tested. This allows a quick and simple verification of set pressure while the valve remains in service. To use the field test connector, the following additional equipment is required and must be provided by the customer: external test medium, e.g. by a pressure cylinder pressure gauge Customer benefit: No plant shutdown necessary for set pressure testing No dismounting of valve necessary. Technical data: Material: 16L / 1.4404 Connection size: G 1 / 2 male and NPT 1 " female Regular Testing of the Pilot Valve Setting required Pressure Gauge Nitrogen regulator Nitrogen bottle valve Nitrogen bottle Isolation valve Connection Valve Test Plug Vent valve 2 Pilot Supply Filter Option code R0 Operating condition: The POSV is used for applications involving dirty medium which require shorter maintenance intervals. These are undesirable. Solution provided: For dirty medium service, a pilot supply filter is available to prevent plugging of the pilot valve and tubing. The filter is suitable for liquid and gaseous media. With the filter added, the filter area is enlarged by a multiple in comparison to the standard pilot valve filter that is integrated into the inlet piping to the pilot valve. The maintenance cycles depend on the following conditions: 1) frequency of operation of the POSV 2) how dirty the medium is Customer benefit: Extended maintenance intervals of the POSV. Dirty Medium Service Technical data: Housing material: 16L / 1.4404 Mesh size: 2µm 1

Accessories Manual Blowdown Option code R2 (blowdown to atmosphere), R24 (blowdown to main valve outlet) Operating condition: The lifting of the piston shall be tested without switching of the pilot valve. To achieve a piston lift the dome volume must be released manually and refilling of the dome must be avoided. The testing of the piston may be required when the medium tends to block the piston. Manual blowdown cannot be used for set pressure testing. Solution provided: The manual blowdown allows lifting of the main valve by bypassing the pilot valve. Thus, the piston dome pressure can be discharged: 1) to atmosphere (Option Code R2) or 2) to the main valve outlet (Option Code R24) Customer benefit: No plant shutdown necessary to test valve lifting No dismounting of the safety valve necessary for testing purposes Valve Lifting Test without Actuation of Pilot Valve required 4 Remote sensing Option code R28 Operating condition: Due to an unfavourable position or length of the inlet pipe excessive pressure loss may occur. This can lead to chattering of the safety valve especially with Pop Action POSVs and the safety valve cannot discharge as much medium as required. This may also damage the safety valve. Solution provided: The pilot valve pressure pick up is piped to a location which is remote from the main valve. The pilot will operate independently of a possible pressure loss in the inlet pipe. The tapping point must be chosen so as to avoid pressure loss resulting from flow influences. LESER supplies the plug at the main valve and the fitting (NPT ") for the customer remote sensing pipe to the pilot. The pipe itself and its welding to the system must be provided by the customer. Parameters determining the maximum length of the inlet pipe are the pipe diameter, the static height of the medium and the viscosity of the medium. Customer benefit: No reworking of inlet pipe necessary in case of high inlet pressure drop. Inlet pressure drop Sealing Accessoires Option code see page 69 NACE requirements Option code R0 LESER offers two different types of discs for different applications to achieve optimum tightness: For material details see page 29.

Sour Gas Applications (NACE) LESER Pilot Operated Safety Valves (POSVs) are available for sour gas (H 2 S) service. Regulatory Requirements The material requirements for hydrogen sulfide (H 2 S) service (sour gas service) are specified in the NACE standards, MR01/ISO 116 (Upstream processes), and MR010 (Downstream processes). Since the body of the pilot valve is manufactured from stainless steel, only the spring in the pilot valve of the Series 810 Pop Action POSV and the dome spring in the main valve need to be replaced for compliance with NACE MR01 standard. Standard MR01/ISO 116 MR010 Application Upstream processes Downstream processes (Refineries) Content Material Carbon Steel Austenitic Stainless Steel (16 SS) Petroleum and natural gas industries Materials for use in H 2 S-containing environments in oil and gas production Rigid requirements for materials resistant to SSC for petroleum production, drilling, gathering, flow line equipment and field processing facilities to be used in H 2 S bearing hydrocarbon service Applies to upstream processes (gas production and treatment) 22 HRC max. and more stringent welding requirement Maximum hardness of 22 HRC Materials resistant to Sulfide Stress Cracking in Corrosive Petroleum Refining environments Provides a standard set of requirements for materials used in sour petroleum refinery equipment Applies to downstream (e.g. refining and gas processing) environments (broader range of sour environments) No base metal hardness requirements on P-No. 1 Group 1 or 2 (WCB, A10 forgings, LCB) Maximum hardness of 22 HRC No temperature limitations The following parts of the LESER POSV are affected by NACE sour gas standards requirements. Parts with a check mark are compliant with the relevant standard (Option code R0).
