[Valve features]
       YX741X diaphragm adjustable pressure / pressure regulating valve is installed in the high-rise building water supply and drainage pipeline, the inlet pressure is reduced to a required outlet pressure of the special valve. The valve outlet pressure to rely on its own energy remained stable in the set value, the outlet pressure is not due to changes in inlet pressure and flow changes, with a self cleaning filter inlet and valve control system, the use of fluid properties, the proportion of larger diameter larger suspended particles will not enter the control system to ensure the system circulation smoothly, so that the valve can run safely and reliably. The system is sensitive and has long service life.

[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.
