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 cracking pressure (20 psi ±30%), valve shuts off. Ball Check Valve prevents reverse flow where leak-tight shut-off is not mandatory. When differential drops below cracking pressure, valve closes.
