High Pressure Swing Check Valve manufacturer, factory and supplier. High Pressure Swing Check Valve is used for high temperature high pressure boiler steam system, High Pressure Swing Check Valve  is pressure self-sealing valve cover, also under pressure to ensure good sealing performance,spring loaded to ensure that even in the low-pressure sealing performance when the same good. High Pressure Swing Check Valve Pressure rating from Class 150 to Class 2500,PN16 to PN420.

A basic High Pressure Swing Check Valve consists of a valve body, a bonnet, and a disk that is connected to a hinge. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent backflow.

The disc inHigh Pressure Swing Check Valve is unguided as it fully opens or closes. There are many disk and seat designs available, in order to meet the requirements of different applications. High Pressure Swing Check Valve  allows full, unobstructed flow and automatically closes as pressure decreases. High Pressure Swing Check Valve is fully closed when flow reaches zero, in order to prevent backflow. Turbulence and pressure drop in the valve are very low.
