400X Flux Control Valve Flange End 1.6mpa Water Conservancy Valve

Introduction

400X Flow control valve is a valve used in the parallel water supply system of fire water and domestic water to adjust the water supply direction

Structure and use

The 400X Flow control valve is composed of main valve, flow regulating valve, needle valve, pilot valve, ball valve, micro filter and pressure gauge. Hydraulic automatic operation is used to control and adjust the opening of the main valve to keep the flow through the main valve unchanged.

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

This series of valve products are widely used in high-rise buildings, living quarters and other water supply pipe network systems and 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 room, and flows out of the main valve control room to the outlet through the pilot valve and ball valve. At this time, the main valve is fully open or floating. Set the flow regulating valve on the upper part of the main valve to set a certain opening of the main valve. By adjusting the needle valve opening and the pilot valve spring pressure, the main valve opening can be maintained at the set opening, and the pilot valve can be automatically adjusted when the pressure changes to keep the flow unchanged
