1 WECO VAVE Cast Steel & Pressure Seal Swg Check Valves

2 Swg Check Valve, BB, CS Design The cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API00 & D.BS EN 0 and generally conform to American Society of Mechanical Engeers standard ASME B.. Valves are available a complete range of body/cover materials and trims. Ranges of Materials Standard body/cover 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. Available Modifications For Cast Steel Valves Trim changes End connection modifications Packg and gasket changes Operator mountg andwheel extensions Pressure equalizg Customer specified coatgs Weld end bore changes Oxygen & chlore cleang & packagg A Eyebolt For 0b",00b", 00b",00b/00b/ 00b" & over.

C End Connections A choice of flanged, RTJ flanged or buttweldg end for pipg flexibility. D to Jot E Outside ever And Weight F s CU weighted mechanical accumulator A male and female jot or tongue and groove jot is used 0b to 00b valves. Rg jot is used the body to cover connection 00b &higher rated valve.s All external hge p swg check valves " and smaller are available with an optional outside lever and weight, ternal hge available with all swg check valves. Separate heavy duty, full ported rgs for easy matenance. Screwed or welded connection to body. This design can be used to either dampen or assist closg of the check valve disc dependg on orientation. by usg the hydraulic control unit to buffer action the disc, the valve opens at lower flow rates.
