Overview Of Cast Steel Gate Valve

    Casting gate valve opening and closing parts is the gate, the direction of movement of the gate and the fluid direction perpendicular to the gate valve can only be fully open and fully closed, can not be adjusted and throttling. The gate has two sealing surfaces. The two most commonly used mode gate valves are wedge-shaped, and the wedge angle varies with the valve parameters, usually 50, and 2 ° 52 'when the medium temperature is not high. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce trace deformation of the gate to improve its craft, to make up the sealing surface angle in the processing of the deviation, The plate is called a flexible gate.Cast Steel Gate Valve

    Cast steel gate valve: all with metal steel casting into the casting of the gate valve collectively referred to as cast steel gate valve. And cast steel gate valve also corresponds to the cast iron gate valve, forged steel gate valve, malleable cast iron gate valve. Cast steel gate valve: According to the material is divided into carbon steel gate valve, stainless steel gate valve, low alloy steel gate valve (high temperature chrome molybdenum steel this category), low temperature steel gate valve. All kinds of cast steel gate valve and a variety of specific steel grades commonly used as follows: 1, carbon steel gate valve casting grades are: WCA, WCB, WCC, LCB, etc .; applicable temperature -46 degrees ~ 425 degrees. 2, stainless steel gate valve Casting grades: 301 stainless steel, CF8 stainless steel (corresponding to forging 304 stainless steel), CF8M stainless steel (corresponding to forging 316 stainless steel), etc .; applicable temperature -198 degrees to 816 degrees. 3, low-alloy steel sub-high-temperature alloy steel and high-strength low-alloy steel, which is often said that high-temperature alloy steel chrome molybdenum steel.Cast Steel Gate Valve

Chrome molybdenum steel gate valve grades: ZG1Cr5Mo, ZG15Cr1MoV, ZG20CrMoV, WC6, WC9, C12A and so on. Applicable temperature of 550 degrees to 750 degrees. The temperature of each specific grade material is different, depending on the actual working conditions.Cast Steel Gate Valve

    Misunderstanding that in the valve procurement, said the cast steel gate valve is usually referred to as WCB grade carbon steel gate valve, because at the earliest time when the steel castings are not as rich as now, when it comes to cast steel gate valve only WCB this material is good, time For a long time the default cast steel gate valve is WCB carbon steel gate valve, WCB carbon steel gate valve is also the oldest and most widely used one of the valve structure.Cast Steel Gate Valve
