[Valve features]
       900X emergency shut-off valve is a water supply system for parallel fire water and domestic water, which is used to adjust the direction of water supply. When the fire occurs, the fire need a lot of water, 900X emergency shutdown valve immediately cut off the water, ensure adequate fire water; when the fire to stop the water pressure decreases, the valve automatically opens, a normally open state, restoration of water supply. The valve does not need to set up another special fire water supply network, which greatly saves construction cost and water consumption. Valve control sensitivity, safe and reliable, simple debugging, 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.
