[Valve features]
       ZLF self balancing valve, is a use of pressure medium itself to carry out self regulation so as to maintain constant flow through the controlled system of the ZLF valve, self balancing valve with flow indicator, can be adjusted online, flow control for non corrosive medium heating and air conditioning system. A one-time test adjustment before operation allows the system flow to be automatically constant at pre-set settings. The utility model has the advantages of accurate flow regulation, simple operation, stable operation, reliable performance 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.
