The 400X flow control valve is a multi-function valve that uses high-precision pilot mode to control flow. It is suitable for the distribution pipe to control the flow and pressure of the pipeline, keep the predetermined flow unchanged, limit the excessive flow to a predetermined value, and appropriately reduce the upstream high pressure, even if the upstream pressure of the main valve changes, it will not affect the downstream flow of the main valve. The valve changes the principle of the conventional throttle valve using orifice plate or purely mechanical reduction of the basin area, using the relevant pilot valve to minimize the loss of energy in the throttling process. In case of emergency, the 400XA flow control valve can completely cut off the flow and avoid loss. High control sensitivity, safe and reliable, easy debugging, long service life.
