2.Feature

400 x flow control valve consists of the main valve, flow regulating valve, needle valve, pilot valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, control and adjust the opening of the main valve, made by the main valve flow rate remains constant.

400 x flow control valve with hydraulic control on our own efforts, do not need other devices and energy, easy maintenance, stable flow control. 400 x flow control valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering.

When the valve from the inlet water supply, water flows through a needle valve in the main valve control room, and after a pilot valve, ball valve, from the main valve control room to export, the main valve in the fully open or floating state. Setting the upper master valve flow control valve, can be set in a main valve opening. Adjust the opening of needle valve and regulating valve spring pressure, can keep the main valve opening in setting the opening, and pilot valve to automatically adjust when pressure changes, the flow rate unchanged.
