1-inch Y swing check valve

The Milwaukee Valve 507 is a bronze-body check valve with a Y swing mechanism and chrome-cobalt seals. It handles water at 600 psi and 150 degrees F, steam at 300 psi WSP, and operates from -20 to 550 degrees F. Rated flow is 31 gpm through a 1-inch FNPT x FNPT connection.

Check pipe threads and cracking pressure

Verify that the existing piping uses 1-inch female NPT threads and that the 0.750 to 1.000 psi cracking pressure suits the system head. Confirm the fluid temperature stays within the -20 to 550 degrees F range and that pressure does not exceed 600 psi water or 300 psi steam. The overall length is 3.6875 in.

Horizontal or vertical mounting

The valve installs in either horizontal or vertical orientation, leaving layout flexibility. Its bronze body and seat resist corrosion in water and steam service. The Y swing design allows full flow with minimal pressure drop, freeing capacity for other fixtures on the same line.
