1/2″ Bronze Swing Y Check Valve

This 1/2″ bronze swing Y check valve provides one-way flow control in plumbing and hydronic systems. The Y-pattern body reduces turbulence while the swing disc opens under forward pressure and seals against reverse flow. Rated for water up to 400 psi at 150 °F and steam up to 200 psi WSP, it suits residential and light-commercial installations. The valve operates from -20 °F to 550 °F.

FNPT Connections and Horizontal Mounting

Verify that your piping uses 1/2″ female NPT threads on both ends to match the FNPT x FNPT connections. The valve must be installed in a horizontal orientation to ensure proper disc operation. Confirm that system pressure stays within the 400 psi water and 200 psi steam limits and that fluid temperature remains between -20 °F and 550 °F. The cracking pressure range of 0.500 to 0.750 psi determines when the disc begins to open.

Sustained High-Temperature Service

Under continuous load the bronze body and bronze seat maintain sealing integrity at temperatures up to 550 °F and pressures up to 400 psi for water service. The chrome-cobalt seal material resists wear during prolonged cycling. Flow capacity reaches 10 gpm with minimal pressure drop across the Y-pattern design. The valve is not intended for vertical mounting or for applications exceeding the stated pressure-temperature ratings.

Questions about this item

What comes with the 508 valve and do I need any extra fittings?

The valve body includes bronze construction with FNPT x FNPT threads and a chrome-cobalt seal. You will need matching 1/2 in NPT pipe nipples or adapters to complete the installation.

How do I decide between the available cracking-pressure options?

The valve operates between .500 and .750 psi cracking pressure; choose the lower end for gravity-fed lines and the higher end when back-pressure must be kept to a minimum.

What does the 10 gpm flow rating mean when the valve is installed in a hot-water system?

At 150 °F and 400 psi water pressure the valve passes up to 10 gpm, so size the pump and piping to stay within that flow for reliable check-valve operation.
