Flow control valve QP400X

Structure and use

 

The valve adopts high-precision pilot-controlled flow, which is suitable for controlling flow and pressure pipelines, keeping the predetermined flow rate constant, limiting the excessive flow rate to a predetermined value, and appropriately reducing the upstream high pressure even if the pressure upstream of the main valve changes. It also does not affect the downstream flow. The valve changes the conventional throttle valve and the principle of using the orifice plate or purely mechanically reducing the drainage area, and uses the relevant pilot valve to minimize the loss of energy during the throttling process. The control is sensitive, safe and reliable, simple to debug and long in service life.
