Features

1, the gate has two sealing surfaces, the sealing surface to form a wedge, wedge angle varies with the valve parameters, usually 5 °.

2, wedge gate valve sealing principle is based on the wedge gate on the two sealing surfaces and the valve body when the two sealing surfaces wedged in close combination, so as to achieve sealing performance.

3, wedge-type gate valve according to the stem-driven gate opening and closing of the different ways, can be divided into Ming rod valve (lifting rod gate valve) and dark rod gate valve (rotary rod gate valve).

4, wedge gate valve structure according to the different forms can be divided into flexible gate valve and rigid gate valve.

5, the valve body is molded, the valve body and the valve cover are bolted, the flange is wound with a gaskets gasket, the customer can also use the metal ring connection when there are special requirements.

6, the channel is smooth, the flow coefficient is small. Sealing surface erosion by the media and erosion of small.

7, the sealing surface of alloy steel or carbide, wear-resistant, anti-abrasion performance.

8, using flexible graphite packing, reliable sealing, light and flexible operation.

9, the medium flow is not restricted, does not disturb the flow, does not reduce the pressure.

10, the shape is simple, the structure of short length, manufacturing technology is good, a wide range of applications.
