Check valve is used in stainless steel pipe system to prevent reverse flow.

Working Principle

The valve opens when the pressure below the valve plug exceeds the pressure above the plug plus spring force

The valve close when pressure equalization has been achieved

A higher counter pressure will press the valve plug against the seat and makes the valve sclosed

Material
