Flow Control Valve

400X flow control valve consists of main valve, flow control valve, needle valve, guide valve, ball valve, micro filter and pressure gauge. With hydraulic automatic operation, the opening of main valve is controlled and adjusted to keep the flow through the main valve unchanged.
This product uses hydraulic self-control, does not need other devices and energy, easy maintenance, stable flow control.
This series of valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
Working principle
When the valve feeds water from the inlet end, water flows through the needle valve into the main valve control room, and flows out of the main valve control room through the guide valve and ball valve to the outlet. At this time, the main valve is in full open or floating state. The flow regulating valve on the upper part of the main valve can be adjusted to set a certain opening for the main valve. The opening of needle valve and the spring pressure of guide valve can keep the opening of main valve at the set opening, and the guide valve can adjust automatically when the pressure changes, so as to keep the flow rate unchanged.
