  • Ordering Process

The 400X flow control valve consists of a main valve, a flow control valve, a needle valve, a guide valve, a ball valve, a microfilter and a pressure gauge to form a hydraulic control nozzle system. Using hydraulic automatic operation, control and adjust the opening of main valve, so that the flow of the main valve remains unchanged.

This product uses hydraulic self-control, does not need other devices and energy, easy maintenance, flow control stability.

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, water flows through the needle valve into the main valve control room, and flows out of the main valve control room to the outlet through the guide valve and the ball valve. At this time, the main valve is in a fully open or floating state. Setting up the flow control valve on the upper part of the main valve can set a certain opening degree for the main valve. By adjusting the needle valve opening and the guide valve spring pressure, the main valve opening can be maintained at the set opening, and the guide valve can be automatically adjusted when the pressure changes, keeping the flow unchanged.
