Flanged Swing Check Valve DN25-DN300 PN16-PN40 for Vacuum Pump, Compressed Air, Gas and Water Systems
Flanged swing check valves are automatic valves that open with forward fluid flow and close automatically with reverse flow. The pressure of fluid passing through the system opens the valve, while any flow reversal securely closes it to prevent backflow.
