EXECUTION OFFSET FROM CENTRE OF VALVE OFFSET FROM CENTRE OF SEAT VALVE CENTRE LINE SHAFT CENTRE LINE Valve body is solid, heavy duty. Seat Retainer construction allows Gasket conforming to API 609. Optimal disc geometry and cavity free flow passage offers minimum flow resistance and high Cv values. Heavy duty pins connecting valve shaft to disc avoid lost motion under high torque conditions. Long life, easy field replaceable seat placed in body, away from flow stream, provides bubble tight shut off. Valves are equally suitable for control and tight shut off applications. Low friction bearings provide maximum radial support for higher shaft loads. The PTFE lined bearings having low coefficient of friction minimizes operating torque and reduces actuator size. They are slip in-place type, easy for assembly and disassembly. Seat options includes PTFE, EPDM, Viton Soft Seats and flexible MetalSeats to suit a variety of fluids and applications. Recommended for critical applications including high temperature services, throttling steam control, liquid services, gas applications, vacuum applications, corrosive fluids, refinery services, chemical services, hydrocarbon services, etc. SPECIFICATIONS CONSTRUCTION WAFER-LUG-DOUBLE FLANGED VALVE SIZES 2-1 / DN 50 - DN 0 RATINGS CLASS 150 - CLASS - CLASS (EQUIVALENT TO DIN) DESIGN STANDARD API 609 - ANSI B 16.3 - ANSI B 16.5 TESTING STANDARD API 598 - FCI 70.2 SEAT LEAKAGE OPTION CLASS VI FOR PTFE - EPDM-FKM SOFT SEATS - CLASS IV FOR FLEXIBLE METAL SEATS FLOW DIRECTIONAL BI DIRECTIONAL CONFORMITY TO CODES DESIGN & MANUFACTURING API 609 CATEGORY B - BS 5155 - API 607 (FIRE SAFE) FACE TO FACE DIMENSIONS API 609 - BS 5155 - BS EN 558-1 - ISO 5752 FLANGE DIMENSIONS ANSI B 16.5 (TILL DN / 2 ) - ANSI B 16.7 (> DN / 2 ) PRESSURE TEMPERATURE RATING ANSI B 16.3 VALVE INSPECTION API 598 - FCI 70-2 2
SEAT DESIGN OPTIONS Most suitable for high consistency fluids having suspended hard particles, for erosive services, for high temperature services > to 550 C. Die pressed stainless steel seats with inbuilt flexible property gives Class IV leakage with minimal torque requirements FLEXIBLE METAL Flow from Seat Retainer Side The lip shaped PTFE Seat moves axially in the direction of flow with the assistance of line pressure. The tightness between seat and disc increases with increased in-line pressure. In case of fire, soft seat material disappear and tightness is ensured by the metallic back-up lip. FIRE SAFE DESIGN Flow from Shaft Side With the line pressure acting on the disc, it tries to move towards the seat which is supported by Seat Retainer. Seat does not move giving simple leak tight seal.
