200P(Y11X type) water pressure reducing valveDetailed product description：

The (Y11X type) 200P water pressure reducing valve sets the outlet pressure by adjusting the adjusting bolt to adjust the spring pressure. This product has smooth and sensitive pressure reduction and stabilization actions.
(Y11X type) 200P water pressure reducing valve is suitable for high-rise buildings and unit water supply pipelines, as well as supporting pilot valves for hydraulic control valves.
The (Y11X type) 200P direct acting diaphragm pressure reducing valve is mainly composed of diaphragm, regulating spring, valve seat, valve disc and other parts. It uses the diaphragm to sense downstream pressure changes, drives the valve disc, and changes and controls the valve opening to achieve pressure reduction and stabilization functions.
