400X flow control valve

Product Overview

400X Flow control valve is a multi-function valve which adopts high-precision pilot mode to control flow. It is suitable for the pipeline where the flow and pressure of the distribution pipe need to be controlled. The excessive flow is limited to a predetermined value and the upstream high pressure is appropriately reduced. Even if the pressure in the upstream of the main valve changes, the flow downstream of the main valve will not be affected. Instead of the conventional throttle valve, the principle of using orifice plate or purely mechanical reduction of drainage area is changed, and the relevant pilot valve is used to minimize the energy loss in the throttling process. In case of emergency, 400X flow control valve can completely cut off the flow and avoid loss. It has the advantages of high sensitivity, safety and reliability, simple debugging and long service life.

Structural characteristics

1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is double sealed by sealing gasket and sealing ring without leakage.
3. Double guide of valve body, piston cylinder and piston ensures stable and reliable movement.
4. All stainless steel piston cylinder, integral casting piston and NBR sealing ring. Perfect combination greatly prolongs service life.
5. The detachable valve seat with advanced technology has ingenious structure, novel conception and convenient maintenance and replacement.
6. For the piston cylinder with guide hole, properly increase the resistance to make the piston movement more stable.
