1 Cast Steel & Staless Steel Wedge & Flat Gate Valves PGE0

2 Gate Valve, BB, CS Design ED cast steel gate valves are designed and manufactured to provide maximum service life and dependability. ll gate valves are full ported and meet the design requirements of merican Petroleum Institute standard PI&PI D,British standard BS& BS EN and generally, conform to merican Society of Mechanical Engeers standard SME B.. Valves are available a complete range of body/bonnet materials and trims. Ranges of materials Standard body/bonnet materials clude ne grades of carbon, low alloy and staless steels. For special applications they can be supplied other grades of alloy and staless steel. There's a full range of trim materials to match any service.optional packg and gasket materials are available for a full range of service conditions. vailable Modifications For ED Cast Steel Valves Trim Changes End Connection Modifications Packg and Gasket Change Operator Mountg andwheel Extensions Pressure Equalizg ByPass Customer Specified Coatgs Weld End Bore Changes Oxygen & Chlore Clearg & Packagg B W G E YS SBER DBER F C STD OD IVE OD STD PCKING NTERN RING G D INT,YOKE SPIT YOKE FFJ TGJ RTJ E PSB BB WB TED I RF RTJ FEX SOID SPIT J Operation arge handwheels for easy operation.also a v a l i a b l e with gearg.motor actuators, pneumatic or hydraulic actuators for more difficult services.

Of the metal to metal sealg, there is a grease jection structure outside the valve, grease jects the sealg part through the seat, this way achieves the aim of zero leakage.
