400X

400X flow control valve is a kind of multi function valve with high precision pilot control flow. Need for control of water distribution pipeline flow and pressure to maintain the same scheduled traffic, too much traffic will be limited to a predetermined value, and appropriate the upstream pressure Zang low, even the king of valve upstream pressure changes, it will not affect the flow downstream of the main valve. The valve changed the conventional throttle valve principle using orifice or pure mechanical area of Zang small watershed, the pilot valve, to minimize the energy during throttling loss. In case of emergency 400XA flow control valve can be completely cut off the loss of flow. The control sensitivity is high, safe and reliable, the debugging is simple, the service life is long.
