Water pressure reducing valve

Water pressure reducing valve is an automatic regulating valve, whose core function is to reduce and stabilize the high and unstable fluid pressure at the inlet end to the required lower pressure value at the outlet end. It mainly controls the overcurrent area by sensing changes in the pressure on the outlet side and automatically adjusting the opening of the valve disc, thereby consuming excess pressure energy and achieving stable output. Its main structural types include direct acting (using springs and diaphragms to directly sense and adjust) and pilot operated (using pilot valves to amplify control signals, with higher accuracy, suitable for larger flow rates and pressure differentials). Valves are usually equipped with pressure regulating devices, allowing users to set the outlet pressure within a certain range. Kaiweixi Valve Group mainly produces water pressure reducing valves such as direct acting spring pressure reducing valves, diaphragm pressure reducing valves, piston pressure reducing valves, hydraulic pressure reducing valves, branch pressure reducing valves, pressure reducing valves with pressure gauges, and self operated pressure reducing valves, which are widely used in building and domestic water supply systems, fire water supply systems, industrial production water supply pipelines, and agricultural irrigation. Water pressure reducing valves are essential control equipment for ensuring the safe, stable, efficient, and economical operation of water supply systems.
