4 FETURES V Features Control Seal ouble lock and leed Valves Friction Free n important aspect of a valve is the sealing mechanism. lmost all valves, like standard all, Gate and utterfly valves have their sealing mechanism based upon shear force, friction and tearing. The Control Seal sealing mechanism is based upon a radial movement only. The sealing is not liable to shear, friction or tearing. This means no abrasion on the seal and compared to other types of valves, results in an exceptional long lifetime. ouble lock and leed Control Seal valves have a double block and bleed function up and downstream. Normally this can only be achieved by using two (2) valves and a spool piece with a drain valve. The use of a Control Seal ouble lock and leed Valve will save cost, space and maintenance for a long period. In-Line Maintenance and Service s the Control Seal valve is designed for easy and low cost maintenance, stem packings can be adjusted while the valve is in service. ll valves are executed with a back seat. ottom and top entry is possible while the valve is inline. No special tools are required. Non-Slam The self-locking operate mechanism on all Control Seal valves provides that the closing member (plug) cannot rotate due to line forces. Therefore there is no danger of line slam, shock or injury to personnel. Fire Safe The Control Seal valves have been Fire safe tested by independent laboratories and have passed the test to S 6755 part 2, PI 6F successfully & ISO These tests have been wittnessed by Lloyds on several valves. dvantages of the Control Seal esign Friction free opening and closing, increasing the lifetime of the valve. Corrosion and wear resistant materials are used on the closure members. ottom and top access for inline inspection and maintenance. djustable stem packing while the valve is in service. ll valves are executed with a backseat, which gives the possibility to renew stem packing under pressure. Non lubricated seal. Pressure independent sealing. No coupling cam in the stem construction. Topworks according to ISO 5210 Optional Valve Executions Control Seal valves can be supplied in a variety of materials and are also available in accordance with IN standards. Stem extensions and gas column for cryogenic service Control Seal ouble lock and leed Valves can be supplied with various types of Viton, which depends on the medium. For remote controll electrical, pneumatic and hydraulic actuators can be installed. ouble lock & leed Valve pplications ouble lock & leed expanding plug Valves are often used in the following applications: Fiscal metering systems for gas and oil Ship and truck loading services Tank storage Transport pipeline services Clean hydrocarbon services viation fuel services MTE services 02

5 W IT WORKS Opening and Closing Sequence V 1. Open Valve fully open. Seating slips are protected from flow path.. ouble lock and leed Valve seated. Resilient seals have been compressed. Resilient seals cannot be damaged by operator over-torque. ouble block and bleed function can be tested by opening the bleed valve. 2. Start to close Plug is rotating. There is no contact between body and seating slips. 5. Start to Open Valve starts opening. Plug moving up, retracting slips from the body seats. Strong dovetail and stems retract the slips. Plug is kept centred in body by top and bottom bushings. g 3. Expanding Plug / slips have rotated 90. Plug starts expanding slips. Slips only move perpendicular to body seats. Plug / slip assembly is kept centred in body by top and bottom bushings. 6. Slips retracted Slips have been retracted prior to rotation. (Further workings as figure 1 and 2 in reversed order). 03

6 LEE SYSTEMS LEE SYSTEMS FOR V utomatic ody leed () The Control Seal ouble lock and leed Valve automatic body bleed is actuated when the valve is closed. s an option the isolating valve can be provided with lock open to avoid any human error. Caution: When the ouble lock and leed Valve comes to its closed position, a cam opens the utomatic leed Valve allowing fluid to escape. s the valve reaches its fully closed position, the spurting liquid should cease, showing positive verification of double seating. proper drain system is required as spilled liquid could be hazardous. Manual leed Valve with Gauge (MV-G) manual bleed valve connected with gauge can be provided when emission is undesirable. The gauge will indicate the cavity pressure and the seal tightness. Note: ody pressure can be increased due to thermal effects, which can indicate false leakage. Manual leed Valve (MV) leed valve for manual operation. The Control Seal ouble lock and leed Valve must always be bleeded in closed position. The MV is the most simple bleed system. Thermal Relief Upstream with Gauge (TRU-G) To avoid body pressure due to thermal expansion, a relief valve with gauge can be provided. This means no emission to the atmosphere and no sump system is required. Relief always set on 25 psi. Thermal Relief Upstream (TRU) With this system on the Control Seal ouble lock and leed Valve, the thermal relief valve releases the overpressure from the body cavity which may be caused by thermal expansion. The system releases from the body cavity to the upstream side of the valve. Manual leed & Thermal Relief (MTR) This principle is the same as that of the TRU, however with the possibility to check the integrity of the ouble lock and leed Valve manually. Note: The relief valve is set to open at 25 psi on all valves regardless of their working pressure. With the Control Seal ouble lock and leed Valve closed, the relief valve will open at 25 psi above upstream pressure. This system functions only when the Control Seal V is closed and the isolation valve is open. Caution: ll automated Control Seal ouble lock and leed Valves require some form of body pressure relief (TRU / MTR / / MV-G / TRU-G), otherwise the valve may be difficult to open or may stick in closed position. 0
