China Stainless Steel Vertical Check Valve manufacturer Xinhai offers SS Vertical Check Valves, DN15-200, 2.5Mpa-4.0Mpa, fluid nitrose, oil, acids etc.

Key Specifications / Features

Normally, stainless steel vertical check valve is closed. The pressure of medium at the entrance of pipe lines overcomes the resistance of spring, opening the valve. When the pressure of entrance is lower than exit, spring pushes the spool to the seat, closing the valve to avoid refluence of medium and taking effect as non-return. The spool of check valve is supported by spring so it can be installed vertically or horizontally.
