[Valve features]

       HH46X, HH48X, HH49X silencing slow closing check valve series products can be used in water, sewage, water and other media on the drainage pipeline, which can prevent the media back, but also can effectively limit the destructive water hammer, ensure the safe use of pipeline. The utility model has the advantages of novel structure, small size, light weight, small fluid resistance, reliable sealing, stable opening and closing, wear resistance, long service life, oil pressure, slow closing, no influence by medium, good energy saving effect, etc..

[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.
