Pressure Control Valve

Automatic pressure control valve use the balancing principle of hydraulic pressure and spring force to adjust the pressure of the hydraulic system and control other pressure related actions, Its main function is: keeping the upstream and downstream system of the pipeline under certain pressure; maintaining pressure differential or pressure ratio between two circuits; when the system exceeds the predetermined pressure, the load will be discharged to play a role of safety protection & controlling the movement of other components through pressure signals. It is widely used in water supply and drainage system, fire protection system and air conditioning system.

Pressure control valves mainly include pressure reducing valve, pressure relief valve, anti-water hammer valve, solenoid control valve, differential pressure valve. Pilot operated pressure reducing valve can guarantee that the outlet pressure of the valve is not affected by the inlet pressure and flow rate. Pressure reducing effect is reliable and stable, and the debugging operation of the pressure reducing valve is simple; Adjustable pressure relief valve can realize the opening and closing of the main valve through automatic pressure induction feedback, ensure the pressure in the pipeline is kept at the set safety value, and realize the function of over-pressure valve opening; Anti hammer water control valve is a kind of pipe fitting function developed independently after extending the function of guide valve, which can reduce the pressure fluctuation caused by pump opening and closing or power failure; Water solenoid control valve is installed on the pipeline as a shutoff valve, which can be closed quickly and can realize remote control and monitoring; Differential pressure bypass valve operates the valve opening and closing by hydraulic power of the medium itself, eliminating the valve sensor and the complex actuating mechanism. Automatic control can be realized by setting well, and the pressure difference of control loop can be kept constant.
