MATERIALS OF MAIN PARTS
400X flow controlling valve is a multifunction valve which use high precision pilot method to control the flow. It’s suitable for the pipe which sparge pipe needs to control the flow and pressure, keep the set flow unchanged, limit the over flow in a preset value, and reduce high pressure of upstream propriety, even upstream pressure of main valve changes, can’t effect downstream flow of main valve. The valve change the normal principle of using orifice plate or machine to reduce flow area, using relative guide valve to minimize the loss of energy during throttling.
