Product Description

Products Details

What’s the Multifunctional hydraulic control valve?

Multifunctional hydraulic control valve is divided into two categories: diaphragm type and piston type. All products are composed of a main valve and pilot valve, piping, pipe fittings and so on. Depending on the purpose, function and place of use, various valves with different performance requirements can be obtained only by changing the installation pipeline of the pilot valve and accessories to form a complete control system.
The multi-function water pump control valve can adjust the opening and closing speed of the hole, and can play the role of backstop, cut-off, water hammer elimination, and protection of the water pump, motor and pipeline during the operation of the system.

Main features and working principle

1) Features:
The product adopts double-chamber drive device and Y-shaped structure. The medium has the advantages of semi-linear water flow in directional motion, large overflow, small pressure loss, stable opening and closing operation, and no pressure fluctuation. The double-chamber driving device can be disassembled as a whole for easy inspection; the diaphragm is made of nylon reinforced rubber, which has a long service life; the valve disc seal can be disassembled, which is more convenient for maintenance.
2) Working principle:
The multi-function water pump control valve is installed on the system pipeline or the pump outlet. During normal operation, the medium at the inlet side pushes the large valve disc up, and at the same time, the medium enters the middle cavity through the flow controller, so that the valve opens quickly; when the movement is stopped, the outlet side The medium enters the upper chamber through the regulating valve, so that the driving device moves down to drive the large and small valve discs to move downward, and the valve is quickly or slowly closed to prevent the medium from flowing back.

Application and Case

Multifunctional Hydraulic Control Valve are used in water system, irrigation system, etc.Water Works Control Valve are used in many projects , such as China Taiwanese Building 101, Xiamen Building,Wuhan Expo Building and other famous landmark projects.
