Pneumatic Flange Single and Double Plate Diversion Hole Natural Gas Gate Valve

The sealing surface of gas gate valve with single and double plate of pneumatic flange is made of hard alloy or ceramic material, which can adapt to the use of high temperature, high pressure and corrosive media. The valve adopts diversion hole structure, with linear flow characteristics, large flow and small pressure drop, can meet the higher flow requirements. The valve operation mode for pneumatic operation, can quickly and accurately control the valve switching state, suitable for high frequency switching operation.
