Products Description
Flange Gate Valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, flange gate valve can only be fully open and fully closed, can not be used for regulation and throttling. Gate has two sealing surfaces, the most commonly used mode gate valve two sealing surfaces form a wedge, wedge angle varies with the valve parameters, usually 50, the medium temperature is not high for 2 ° 52'. Wedge gate valve gate can be made into a whole body, called the rigid gate; can also be made to produce a small amount of deformation of the gate, in order to improve its manufacturability, to make up for the angle of the sealing surface in the processing of the deviation, this gate is called the elastic gate.
