400X flow control valve
400X flow control valve structural features and uses The 400X flow control valve 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. The hydraulic automatic operation is used to control and adjust the opening of the main valve so that the flow rate through the main valve remains unchanged.
This product uses hydraulic self-control, which does not require other devices and energy, simple maintenance and stable flow control.
This series of valve products are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.
Working principle of 400X flow control valve 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 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 degree for the main valve. Adjusting the opening of the needle valve and the pressure of the pilot valve spring can keep the opening of the main valve at the set opening degree, and the pilot valve automatically adjusts when the pressure changes, keeping the flow constant.
