Swing Check Valve is knows as one way valve or non-return check valve. Check valve are used in the pipeline to prevent backflow. The pressure of the fluid passing through a system opens the valve, whie any reversal of flow will close the valve. Check Valves are automatically used one-way flow of media channels, the media only allows flow in one direction in order to prevent accidents.
Usage of Swing Check Valve:
Swing Check Valve is one of the most common and best check valve for general-purpose use. Check Valve is suitable for pipeline which Pressure 1.0 Mpa-42.0 Mpa, Class 150 to Class 1500, Temperature from -196 degree to 540 degree. Different material requirements can meet petroleum industry, chemical industry, hydraulic power industry and power station work conditions. Suitable Medium: Water, Gas and Oil.
Material of Swing Check Valve:
WCB Swing Check Valve, LCB Swing Check Valve, Stainless Steel Swing Check Valve, Duplex Stainless Steel Check Valve, Alloy Steel Ti Check Valve, Bronze Check Valve, Inconel Check Valve, Monel Check Valve, 20# Alloy Steel Check Valve and Hastelloy Check Valve

Installation and Instructions of Swing Check Valve
The swing check valve with pneumatic is installed vertically on the horizontal pipe, and full opened.
Check flow direction and arrow of valve are same way before installing.
The medium passing through the pipeline should not have hard particles to avoid damage to the sealing surface.
The swing check valve is inspected and tested one by one before leaving the factory. The installation unit can be directly tested by pressure or installed.
