[Valve features]

       400X flow control valve, is a high precision pilot style control flow of multi-function valves. Need for control of water distribution pipeline flow and pressure to maintain the same scheduled traffic, too much traffic will be limited to a predetermined value, and appropriate to reduce the upstream pressure, even if the main valve upstream pressure changes, it will not affect the flow downstream of the main valve. The utility model changes the principle that the conventional throttling valve uses orifice plate or automatically reduces the area of the drainage basin, and uses relevant pilot valve to minimize the loss of energy in throttling process. In case of emergency, the 400XA flow control valve can completely cut off the flow and avoid loss. The utility model has the advantages of high sensitivity, safety, simple debugging and 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.
