Bidirectional self sealing knife gate valve adopts an integral valve body design, with pressure sleeves on both sides of the valve seat to protect the flange surface and increase the service life of the valve. The valve seat is in a self tight state between the valve seats when the valve is fully open and fully closed, so that fluid does not remain in the valve chamber. The valve body is equipped with a drain port and a cleaning port, which can clean the fluid trapped in the valve chamber.
○ Reliable cutting off application of bidirectional pressure conditions for ash slurry pipelines in power plants
○ Requirements for bidirectional sealing and isolation of high concentration tailings conveying system in mines
○ The main pipeline of the sewage treatment plant requires bidirectional zero leakage cut-off control valves
○ Safety maintenance partition device for chemical slurry reaction pipeline under bidirectional pressure
○ High sealing gate valve for bidirectional flow condition of papermaking white water recovery system
One way sealed fully enclosed knife gate valve is a structure in which the gate is fully enclosed in the valve chamber for opening and closing sealing.
Bidirectional self sealing knife gate valve adopts an integral valve body design, with pressure sleeves on both sides of the valve seat to protect the flange surface and increase the service life of the valve.
The one-way sealed knife gate valve is a double sealed structure, with a first seal at the valve packing to scrape off dirt on the surface of the gate and prevent debris from flowing up
