Product Description
The structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
Features & Benefits

● The length of the structure is short series, the valve is light in weight, and the pipe support frame can be saved. 

● The valve in the process of opening and closing the gate can scrape off the attached medium by itself, which is conducive to sealing. 

● Knife gate is conducive to cutting off the medium, slagging, valve operation unblocked. 

● Valve adopts clamp connection. Wedge limit provides sealing force and reliable sealing. 

● Wear-resistant bushings of different materials can be provided according to requirements to extend the service life of the valve. 

● Drive device (electric, gearbox, pneumatic, hydraulic) can be optional.
