Wedge gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be used for regulation and throttling. Widely used in petroleum, chemical, thermal power plants and other oil, water vapor pipeline to connect or cut off the medium in the pipeline. (Can not be used as a throttle valve).

Wedge gate valve series gate valve has a small fluid resistance, the sealing surface by the impact of erosion is small, does not change the direction of media flow, do not disturb the flow, pressure drop is small, etc., the applicable pressure, temperature range is wide, is a common cut-off valve, the gate has two sealing surfaces, commonly used mode gate valve two sealing surfaces to form a wedge, the wedge angle varies with the parameters of the valve, usually for 50, the valve is a good choice, the valve has a good rigidity, smooth passage, flow coefficient is small, long service life, the use of flexible graphite packing, sealing is light, easy to operate, and reliable.

Wedge gate valve structure is compact, reasonable design, valve rigidity, channel smooth, flow coefficient is small, sealing surface using stainless steel and hard alloy, long service life, the use of flexible graphite packing, sealing and reliable, light and flexible operation, driving method for manual, pneumatic, electric, gear drive, the structure of the form of resilient wedge single gate, rigid wedge single gate double gate type.
