400 Series Check Valve

Instrument Check Valves are used to make sure that medium flows only in one direction. Check Valves provide unidirectional flow and tight shut-off for liquids and gas with high reliability. When differential drops below the cracking pressure, the valve shuts off. Ball Check Valve prevents reverse flow where a leak-tight shut-off is not mandatory. When differential drops below the cracking pressure, the valve closes.
