■ Features and Applications

The hydraulic control connection system consists of a main valve, a flow regulating valve, a needle valve, a pilot valve, a ball valve, a micro filter, and a pressure gauge. Utilize hydraulic automatic operation to control and regulate the main valve

Open to maintain a constant flow rate through the main valve.

This product utilizes hydraulic self control, does not require other devices or energy, is easy to maintain, and has stable flow control.

This series of valve products is widely used in water supply network systems such as high-rise buildings and living areas, as well as urban water supply projects.

■ Working principle

When the valve supplies water from the inlet end, water flows through the needle valve into the main valve control chamber, and flows out of the main valve control chamber to the outlet through the pilot valve and ball valve. At this time, the main valve is fully open or floating

State. The flow control valve on the upper part of the main valve can be set to a certain opening degree. Adjusting the needle valve opening and adjusting the pressure of the pilot valve spring can keep the main valve opening at the set opening,

And when the pressure changes, the pilot valve automatically adjusts to maintain the same flow rate.
