[Valve features]
       ZYC self operated differential pressure control valve is a kind of self control using the pressure change of the medium itself, so as to keep the valve of the medium pressure difference flowing through the controlled system. The utility model is suitable for the pressure difference control of a heating system adopting a double pipe system. Ensure that the system pressure differential is basically the same, reduce noise, balance resistance, eliminate heat supply network and hydraulic imbalance.

[Adaptive condition]
       Water control valve is the pipe medium pressure as the driving force for opening and closing, regulating valve. It consists of a main valve and attached to the catheter and needle valve, ball valve and pressure gauge, etc. according to the purpose and function of the different places, can be turned into a remote control float valve, relief valve, relief valve closed, flow controller, pressure relief valves, hydraulic control valves, emergency shut down valve.

Hydraulic control valve action:
1, It can be used in domestic water supply, fire fighting system and industrial water supply system.
2, hydraulic control valve to use the pilot valve to control the opening and closing of the valve, saving energy.
3, can replace other valves, large electric device.
4, hydraulic control valve products are widely used in high-rise  buildings, living areas and other water supply network systems and urban water supply projects.
