Product name：Knife Gate Valves
Product Description
Knife gate valve is a kind of knife gate valve, open and close the process of driving device and stem gate coaxial, open the torque is small, easy to operate, with light weight, simple structure, reliable sealing, long service life, can effectively cut off the advantages of the medium in the fiber, its sealing principle is through the gate plate closed to the bottom, the gate bevel cutting surface touches the valve body wedge block makes the gate plate close to the sealing surface to play the sealing effect, and the bottom of the gate bevel cutting surface has the function of cutting off the medium, can also scrape the sealing surface adhesion, automatic removal of debris, stainless steel gate can prevent corrosion caused by a knife gate valve. And the bottom of the gate plate bevel cutting surface has the function of cutting off the medium, so that the valve is not easy to be blocked by debris jam, but also scrape the sealing surface of the adhesion, automatic removal of debris, stainless steel gate can prevent corrosion caused by the seal leakage. Suitable for slurry, powder and granular materials, fibres and other difficult to control fluids, widely used in paper, petroleum, chemical, drainage, food and other industries.


Working Performance.
Knife gate valve has good shearing effect due to the knife gate, which is most suitable for slurry, powder and granular material, fiber and other difficult to control fluids, and is widely used in paper making, petrochemical, mining, drainage, food and other industries. With a variety of valve seats to choose from, and can be equipped with electric or pneumatic actuators according to the needs of site control, to achieve automatic operation of the valve. Knife gate valves have good shearing effect due to the knife gate, and are most suitable for slurry, powder and granular materials, fibres and other difficult to control fluids.
