Z641H Pneumatic Gate Valve product details

Z641H Pneumatic Gate Valve characteristic

1. The gate has two sealing surface, sealing surface form wedge, wedge Angle varies with the valve parameters, usually 5°.
2. The sealing principle of wedge gate valve is the close combination of the two sealing faces on the wedge plate and the two sealing faces on the valve body, so as to achieve the sealing performance.
3. Wedge gate valve can be divided into bright stem gate valve (lifting stem gate valve) and dark stem gate valve (rotating stem gate valve) according to the different way of opening and closing of the gate driven by the stem.
4. Wedge gate valve according to the different structure form of the gate, can be divided into flexible gate valve and rigid gate valve.
5. The valve body is cast, the valve body and the valve cover are connected by bolts, the middle flange is sealed by winding gasket, and the metal ring can be connected when the customer has special requirements.
6. Smooth channel, small flow coefficient.The sealing surface is less eroded by the medium.
7. The sealing surface is made of alloy steel or hard alloy, with good wear resistance and abrasion resistance.
8. The use of flexible graphite packing, reliable sealing, light and flexible operation.
9. The flow of the medium is not limited, no turbulence, no pressure reduction.
10. the body is simple, the structure length is short, the manufacturing technology is good, the application scope is wide.
