General:
Check valve is one kind of valve that can automatically block the backwards flow of gas. It is widely used for steam and liquid application. Check valve has simple structure consisting of valve body, valve flap, spring and spring seat. Its installation is very simple; just clamp it between two flanges. Check valve is opened by the force of hydraulic pressure and automatically closed when this force is discharged.
Features:
� Convenient installation and disassembly.
� Meeting the requirement of medium flow direction. It can be installed in any direction to prevent backward flow.
� Quiet axis direction sealing with good performance, long service lifetime.
� Small starting pressure, small pressure loses.
