[Valve features]
       H104X piston type adjustable pressure regulator valve is installed on the pipeline of high-rise building water supply and drainage system, and reduces the inlet pressure to a required outlet pressure of the special valve. The valve itself rely on energy to maintain stable export value in the set, the outlet pressure is not due to changes in inlet pressure and flow changes, there is a self cleaning filter inlet and valve control system, the use of fluid properties, the larger proportion of larger diameter of suspended particles will not enter the control system to ensure the system cycle smoothly. The valve can run safely and reliably. The system is stable, high strength and long service life. Piston type applies to valves larger than DN450mm diameter.

[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.
