This product is based on our experience of over 60 years Develop what the Customer Requires For this reason we asked him, evaluated his feedback and incorporated the result into the design of this control valve. Progress 3 By developing a digital positioner of the second generation with the option of bidirectional communication. Flexibility Invention of a compact, pipeless a n d v i b r a t i o n r e s i s t a n t positioner mounting which guarantees quick assembly and high reliability for all actuator functions. Efficiency Cost of Ownership Decrease of operating and maintenance cost, (in addition). The SWS-seat (quick changeable trim combination) for example offers the option of a doubleside use by reversing the seat r i n g ( r e s u l t s f r o m t h i s procedure). Environmental Awareness By a stem sealing that meets today's requirements by providing a corrosion resistant stuffing box area Double use of auxiliary energy by using the tried and tested p n e u m a t i c m u l t i - s p r i n g diaphragm actuator with the option of permanent spring case ventilation. Universal Design according to ANSI with standardised trims. Precision A v o i d i n g m i s a l i g n m e n t between actuator and valve guiding by applying of up-todate CNC manufacturing techniques. 10 Control of the "Magic Triangle" Shortening the delivery time, minimising the cost with at the same time higher technical value, improvements and quality. The result is called ECOTROL A new control valve without any compromise. Perfect with regard to quality, efficiency, weight and ease of maintenance-a valve which is unique.

4 ECOTROL The valve series FORBES MARSHALL ARCA-ECOTROL is a robust, compact and lightweight control valve with a pneumatically operated, easy field reversible multi-spring diaphragm actuator FORBES MARSHALL ARCAPAQ 81 and a sturdy, pipeless and vibration-resistant mounted digital positioner. Optional, the actuator can be equipped with a fully enclosed emergency handwheel which is in compliance with general safety precautions (1). The highlight of this valve series is the FORBES MARSHALL ARCA-double-life (quickchangeable trim combination) with the option of a doubleside use by reversing the seat ring (10). Because of its simple geometry the valve seat can be economically produced in different materials like steel, hardened and stellited steel, ceramic, Tungsten carbide, etc., with or without soft sealing. In comparison to conventional designs the speciality of the ECOTROL s soft sealing is, that the PTFE-element is flexibly supported by an additional Elastomer O-Ring. Both sealing elements are located in the seat ring and not as usual in the valve plug. The additional metal-to-metal sealing of plug and seat ring ensures that the PTFE-disc suitable for double side use is not plastically deformed by excessive loads. 8C 6N 6H The remarkable difference between the common screwed-in seat ring and this unique quick-change(able) trim combination, shown in the figures hereinafter, is because of the principle of retaining and sealing the seat ring in the valve body. With a screwed-in seat ring the sealing between seat and valve body is provided by the metal-to-metal contact of two conical faces. Series 8C1 The conical counter-face in the valve body has a slightly different angle so that there is only a theoretical circumferential line contact. The required torque to screw-in the seat ring is individually different depending on the construction and the operating conditions. With the FORBES MARSHALL ARCA ECOTROL valve series the seat sealing is done purely axial and achieved by the method of initial compression. The compression of the sealing elements (6, 11) is limited by the precisely sized recess in the body for containment of the flat gasket. This limits the gasket s compressive loading and guarantees a perfect alignment between the sealing surfaces of plug and seat ring. The self-aligning seat ring (10) is held by the retaining cage (9). The tightness is achieved by transferring a portion of the bonnet-to-body bolting force via the retaining cage to the seat ring. The valve body (1), retaining cage, and seat ring are manufactured on special CNC-machining centres to meet the stringent tolerance of each part. This guarantees the required compression of the sealing elements. Excellent stem guiding is performed by two special guide bushings (4, 8) located as far as possible from each other.

5 The Profitable Solution: ECOTROL "New" the standard spring energised stem seal configuration including a PTFE-V-Ring packing set (5) with an additional micro-sealing element and wiper ring (3). The PTFE-V-Ring packing set is pre-loaded by a stainless steel spring and pressed against the valve stem and the bonnet insert (7). The packing set acts as primary sealing and as a wiper. The valve stem is guided at two locations right before and behind the stem sealing (5). Besides, the extremely reliable sealing performance even under varying operating temperatures, the stem sealing provides minimised static and sliding friction forces in comparison to conventional stuffing box packings. Cost Saving Benefits Excellent performance in liquid and gas applications Extended lifetime due to double-side use by reversing the seat ring (10; upper and lower side) Easy and fast assembly, maintenance without any special tools Low cost performance ratio Prevention of leakage (5) and bypass leakage by a limited compressive load acting on both encapsulated gaskets (6, 11) Multiple material options Optimal flow conditions by seat retaining cage (9) Optional: PTFE-soft seat sealing with back-up O-Ring and metal-to-metal end stop Alternatively to the pipeless positioner mounting: mounting acc. to DIN IEC 534 T6 (NAMUR)

6 Stem sealing Depending on the operating conditions, the stem sealing consists of a special sealing configuration to ensure lowest fugitive emission and minimised friction. The stem and the packing bore provide a super finished surface manufactured by the so-called roller burnishing process. This process compresses the surface and increases its hardness. The Standard Maintenance-free PTFE-V- Ring Packing with a Micro-Sealing Element To guarantee the sealing performance at very low pressures, the PTFE-V-ring packing set is preloaded by a corrosion resistant spring. In normal operation the sealing lips are pressed against the stem and the packing bore relative to the fluid pressure (pressure energised). To resist the internal pressure resulting from alternating operating conditions the V-Ring set is made of different compounds. The outer packing consists of PTFE with a graphite filling and the centre ring is made of pure PTFE. The bottom base ring in the V-Ring set acts as a wiper and just allows a small amount of fluid to reach the micro-sealing element. This final sealing element is made of a special Elastomer material. Its distance from the top wiper ring is equal to the maximum stroke length. While the valve remains in open position, dirt or any kind of stain may accumulate on the stem part right above the top wiper ring. When the stem moves to the closed position some stain may pass the wiper ring, however, it will never approach the micro-sealing element and cause this element to fail. Graphite Stuffing Box A reliable and safe packing assembly requires a homogeneous compression of the entire set of graphite packings. The screwed stuffing box transfers the compressive load to each packing in the stuffing box. This is similar to the hydrostatic principle of pressure distribution in a fluid. To achieve a steady homogeneous compression of all packings, the lower rings must be compressed more than the upper ones during assembly. To realise this, the patented ARCA-OPTIPRESS pre-loading device, activated by the actuator, is recommended. If the packing loading is simply done by tightening the screwed stuffing box there is the risk of an unequal compression of each packing. In such case the upper rings are compressed more than the lower ones due to frictional forces. This leads to an unfavourable non-homogeneous compression of each ring. Since only the top packing seals tightly, it comes to an early leakage in service and the torque demand also increases. As a consequence, the torque transferred from the screwed stuffing box must be applied with care, so that the packing sealing becomes effective, while the hysteresis does not become too high. Bellows Seal Bonnet Hermetically sealing bellows are available for process fluids when no stem leakage can be tolerated (e.g. toxic fluids). The pressure-proof and elastic stainless steel bellows is tightly sealwelded to the valve stem and the upper adapter ring. For safety reasons the construction includes a standard stem sealing as back-up in case of a bellows failure. Between bellows and packing a tapped hole with a plug screw is optionally supplied, either to be used as leak detection, bleed-off, or for inserting a blocking gas. The voluminous bellows housing provides a reasonable flow velocity around the bellows and, therefore, reduces the susceptibility of the bellows against crystallising fluids or polymers. The design is equipped with a built-in twist protection that safely keeps the torque caused either by fluid forces or by improper handling away from the bellows, a guarantee against sudden bellows failure and the resulting shutdown and repair costs. Of course, the FORBES MARSHALL ARCA bellows sealing is in full compliance IS

7 Stem sealing Wear Resistant Bushing To prevent galvanic corrosion between the bonnet stuffing box (carbon steel) and the packing (graphite), all bonnets of valves larger than DN 50 (NPS ") offer a special treated stainless steel bushing. For valves equal or less than DN 50, the bonnet is always made of stainless steel. The bushing with a straight through bore allows superfinishing of the surface which ensures perfect sealing between packing or sealing ring and bushing. The stainless steel bushing avoids or minimises any corrosion and spoiling in the vicinity of the sealing. Bonnet Extension for Cryogenic Service The cross sectional drawing shows the principle design of the newly developed ECOTROL control valve for cryogenic service. The valve plug and stem extension are double guided. The bottom guiding is located right below the valve seat. This guarantees a reliable sealing performance, a vibration free guiding of the plug, and an easy replacement of the guide bushing. Every part that is subject to wear can be individually replaced. The seat is axially restrained by the retaining cage and the top flange. The bonnet extension prevents icing of the packing area. The thin walls of the insulation column and of the stem extension allow only a very low conductive heat flow. In addition, the stem extension pipe is filled with Perlite to reduce convective heat loss to a minimum. The bonnet extension length is based on customer requirements. All cryogenic valves, apart from ARCA's standard valves, are assembled in a clean-room environment. Here, the valves undergo a thorough cleaning process in a subsonic bath followed by a complete dehydration in an air circulating dryer. PED Top Flange Design (8C1) To be in compliance with the European Pressure Equipment Directive (PED) the valve's top flange and actuator yoke (material: austenitic stainless steel) are made of two individual parts. The top flange is permanently attached to the body and untying is unnecessary for dismounting the actuator.

8 Trim Styles Parabolic Plug (Standard) Metal-seated quick-changeable trim combination. Insensitive to impurities with low cavitation design. Fast and easy to produce due to its rotational symmetry. Parabolic Plug with Soft Sealing and Secondary Metal-to-Metal Sealing Soft-seated quick-changeable trim combination The PTFE-soft sealing (for unrestricted use on both sides) is flexibly supported by an additional Elastomer 0- Ring. The additional metal-to- metal sealing of plug and seat ring ensures that the PTFEdisc is not plastically deformed by excessive loads when the plug reaches its final closed position. Parabolic Plug Double-Guided Metal-seated quick-changeable trim combination with top and bottom guiding. This double guiding construction stabilizes stem and plug over the full travel range. Therefore, it is recommended for high pressure drop applications. The additional guiding is located right below the seat ring and can be easily replaced. Most conventional body designs with top and bottom guided trim have a bolted bottom flange which requires an extra body gasket plus the risk of additional external leakage. The ECOTROL one-piece body design eliminates this problem and ensures optimum tightness. Perforated Plug/Perforated Low Noise Cage Metal-seated quick-changeable trim combination. Particularly effective for liquids and compressible fluids at high pressure drop ratios. Liquid flow can cause erosion by cavitation. The flow, directed through the holes of the trim, is divided into numerous jets of cavitating liquid. In the centre of the cage the jets impact and the vapour bubbles collapse. Here, they do not cause any damage to the valve internals and the noise level is also considerably reduced. For more noise abatement a perforated low noise cage is available for all trim designs. Balanced Trim Valves with balanced trims require much lower control forces than valves without balancing. As sealing elements we offer: metallic piston rings Elastomer Quadrings with PTFE support pure graphite

9 Trim Styles/Precautions against Wear and Tear On/Off Plug (Soft-Sealing / Double-Guided also available) This plug is designed where a significant flow rate must be quickly established; also available with soft seat and top and bottom guiding. Stellited Seating Surfaces (hardened to Rockwell C for elevated applications). Excellent Wear Resistant Trim Material SS440C (hardened to > 58 Rockwell C) other harder alloys or special ceramics for extreme applications on request (hardened up to 000/600 HVI). Quick Changeable Trim Parabolic and perforated plug. Quick and easy exchange of throttle without any special tools. Several material combinations possible, in particular for hard metal and ceramic execution. In a control valve the throttling process is principally the conversion of potential energy (pressure) into kinetic energy (velocity). Due to design constraints the maximum velocity occurs at the orifice between plug and seat ring. Especially at high pressure drops, the sealing surfaces and the contours of seat ring and parabolic plug must resist extreme erosive effects caused by cavitation, abrasion and high velocity impingement. Because of their simple rotational symmetry the trim elements can be made of alternative materials providing excellent wear resistance for instance Silicon Nitride, Aluminium Oxide, Tungsten Carbide etc.

12 Easy Plug-In Concept Direct Pipeless Positioner Mounting The positioner can be easily plugged-in within seconds. At the same time the connection for the outlet actuating pressure and the stroke feedback mechanism is provided without any additional part. Rugged, vibration-resistant and pipeless positioner mounting adjacent to the post of the yoke guarantees short stroke feedback elements and, therefore, highest control accuracy. The entire feedback mechanism of the positioner is fully encased between both posts of the yoke. That ensures safe functionality and further incident prevention. The instrument air supply between positioner and actuator is attained through bores inside the yoke. Since this supply system is entirely pipeless the positioner mounting can be enormously simplified. Positioner types C, D, and E provides the option of a permanent ventilation of the spring case by clean exhaust instrument air. Positioner Mounting acc. to DIn IEC 534 T6 (NAMUR)

13 Mounting of Positioner acc. to VD/NDE 3847 ARCA series 81 multi-spring actuators support the standardised positioner mounting per VDI/VDE This interface allows the easy exchange of positioners and solenoid valves made by different manufacturers, without losing the advantages of integrated mounting such as:?high stability even in extreme stress situations caused by vibration and shock?the pipeless supply of control air to the actuator's diaphragm chamber for fail-to-close action (for pipeless fail-to- open action choose actuator type C).?direct mounting of solenoid valves per VDI/VDE 3845 (1998). As special option, the interface is also available with separate block valves for air supply, positioner outlet and solenoid valve outlet. On demand, the valve may be locked, and the positioner / solenoid valve can be exchanged without impact or disturbance to the process itself.

14 Diaphragm Actuator Series 81 Description Pneumatically operated multi-spring diaphragm actuator of the new generation. The actuator is easily field reversible without the need of disassembly. The instrument air supply between positioner and actuator is attained through bores inside the yoke providing more reliability in comparison to conventional designs. This method ensures a safe air supply to the actuator and simplifies enormously the positioner mounting. Furthermore, the combination with the positioner type 84 or the digital positioner of the second generation type 87 provides the option of a permanent ventilation of the spring case by clean exhaust instrument air. During operation there is a minimal overpressure against atmosphere on the rear of the diaphragm plate (spring chamber). This guarantees that during stroke movement no ambient air can be sucked into the spring chamber. This protects the essential inner parts against aggressive atmosphere (like sea air).
