Cast steel pneumatic knife gate valve

Cast steel pneumatic knife gate valveIntroduction:

Pneumatic knife type gate valves can complete the action control and signal output of opening and closing positions by using accessories such as solenoid valves and proximity switches, as well as automatic control of continuous actions. Users can choose according to their actual needs. The nominal diameter is DN50~DN800, and the working pressure is 1.0~1.6MPa. The product is widely used in chemical, coal, sugar, sewage, paper and other fields. It is an ideal sealing valve, especially suitable for regulating and throttling pipelines in the paper industry.

Pneumatic cast steel knife gate valve with pneumatic drive, clamp type connection, parallel rigid single gate plate, valve seat sealing surface made of hard alloy and polytetrafluoroethylene, nominal pressure PN10~16, valve body material made of carbon steel (PZ673H-10C~16C) and stainless steel (PZ673F-10P~16P PZ673Y-10P~16P), with slag discharge function.

Pneumatic knife type gate valveFeatures:

1. Ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.

2. Occupying a small effective space, it can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.

3. The gate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can effectively prevent sealing leakage caused by gate corrosion.

4. The upper sealing filler adopts flexible PTFE, which is reliable in sealing and easy to operate.

5. The gate has the function of a knife, which can effectively block various impurities in the medium.
