Product Introduction:
Gate valve is a like a gate, with the movement direction perpendicular to the direction of the fluid, and gate valve can only be fully open and closed, not adjusted or throttled.
This gate valve is open stem, has two sealing faces, with brass raw material, forming a wedge with a wedge angle varying with valve parameters, usually 50, and 2°52' when medium temperature is not high, it is made into a whole body, so called the rigid gate, it is Installed in the pipeline, as a closed circuit equipment only, not allowed to adjust the flow rate and empty use.
Gate valve with following working principle: turn the hand wheel to open and close the valve plate connected to the stem by the hand wheel and stem thread advance, back, lift or drop, very easy operation.
