Overview
NC2718E is cataloged as a 1/4-inch tube check valve with a 5 PSI designation. John Guest’s current NC2718E-US reference identifies the black acetal version and specifies 5 PSI cracking pressure.
Cracking pressure is the pressure difference needed to start opening the valve, not its maximum working pressure. The referenced valve allows liquid flow in one direction; install according to its flow marking.
Confirm the supplied marking against NC2718E-US. The catalog omits the current reference’s -US suffix.
