Stainless Steel Gate Valve Automatic Open Close Valve Wear Resistance
Product Description:
Stainless Steel Gate Valve is one of the most common opening and closing valves, which uses a gate plate (i.e. opening and closing parts, in which the opening and closing parts are called gate plates or gates, and the gate seats are called gate plate seats) to connect (fully open) or Cut off (fully close) the medium in the pipeline. It is not allowed to be used as a flow interceptor.
The movement direction of the gate is perpendicular to the direction of the fluid. The Gate Valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed through the contact between the valve seat and the gate plate.
During use, you should avoid opening the gate a small amount, because the erosion of the high-speed flowing medium will accelerate the damage of the sealing surface.
