○ The bidirectional self sealing pneumatic knife gate valve uses two rubber valve seats to clamp and press the gate to achieve a sealing effect. When the gate is fully opened, the two sealing valve seats self match and press against each other, forming a fully rubber short pipeline. Combined with the internal pressure of the pipeline, the strength sealing effect is better. At the same time, when the valve is fully open, the gate can be replaced online without the need to remove the entire valve for gate replacement and maintenance, which affects the normal operation of the pipeline. The main feature of this valve is a full diameter rubber sealed seat, which has strong wear resistance and full diameter flow resistance. Suitable for use on industrial and mining pipelines that require wear-resistant valves.
○ Automatic truncation control of bidirectional pressure ash pipeline in power plant ash removal system
○ Remote isolation valves with bidirectional sealing are required for the main pipeline of mine tailings transportation
○ Pneumatic cut-off point for bidirectional flow of main sludge pipe in sewage treatment plant
○ Safety maintenance valve for chemical slurry reaction circulation pipeline under bidirectional pressure
○ Double directional sealed discharge valve for high concentration fiber pulp in papermaking white water recovery system
Pneumatic penetrating plug valve is a type of valve in which the gate and valve seat are always in close contact and sealed. Its principle is that the gate has a circular opening of the same diameter
Bidirectional sealed knife gate valve, with no groove design, adopts a split structure, and an improved polyurethane lined valve seat sealing ring fully protects the valve body from medium erosion
The square sewage pneumatic knife gate valve is sealed between the gate and the sealing surface, mainly with metal sealing. This type of valve is best installed horizontally.
