[Valve features]

       H142X hydraulic water level control valve is a kind of automatic control water tank, water tower height of the water level of the hydraulic control valve. When the water drop exceeds the preset value, the float valve is opened, the piston chamber pressure is reduced, the piston is formed under pressure, this pressure difference valve open water supply operation; when the water level rises to a preset height, the float valve closed, the piston chamber pressure increase the valve to stop water supply. Thus, the setting height of the liquid surface can be automatically controlled to realize the automatic water supply function.

[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.水力控制閥作用：
