type pneumatic knife gate valve opening and closing is ram, ram movement direction perpendicular to the direction of flow and the manual type knife gate valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, wedge type knife gate valve disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, the gate is called elastic disc type knife gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most type knife gate valve is made mandatory sealing, the valve is closed, to rely on outside force forced the ram pressure to the seat, to ensure the sealing surface sealing.
