The steel gate valve body is made of WCB material with delicate appearance. The internal part numerical control lathe machining, carries on the second processing, causes the appearance to be more beautiful.The seat of cast steel gate valve adopts Cr stainless steel and surfacing 507 molybdenum to increase the wear resistance of the seat.
Advantages of gate valve:
1) Small fluid resistance;
2) Small torque required for opening and closing;
3) It can be used on the ring pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted;
4) When fully opened, The sealing surface is eroded by the working medium and is smaller than the globe valve。5) The shape is relatively simple, and the manufacturing process is good.
6) The structure length is relatively small. Usually, the pipeline with a nominal size
