Milwaukee Valve 508 1" Swing Y Check Valve 3.6875 in

Valve Purpose

The Milwaukee Valve 508 is a one-inch Y-pattern swing check valve designed for horizontal piping systems. It prevents reverse flow in water and steam lines for commercial and industrial installations. The bronze body and bronze seat handle temperatures from minus twenty to five hundred fifty degrees Fahrenheit. It suits contractors who need a reliable non-return valve for standard pressure service.

Flow Characteristics

The Y-pattern body reduces turbulence and allows a flow capacity of thirty-one gallons per minute. A cracking pressure range of zero point five zero zero to zero point seven five zero psi keeps the disc closed until sufficient forward pressure builds. Maximum water pressure is four hundred psi at one hundred fifty degrees Fahrenheit, while steam service is rated to two hundred psi WSP. The chrome-cobalt seal material resists wear across the full temperature span.

Installation Notes

The valve measures three point six eight seven five inches overall and connects via FNPT by FNPT threaded ends. Horizontal mounting orientation is required for proper disc operation. No special tools are needed beyond standard pipe wrenches and thread sealant. Installers must verify flow direction arrows and ensure the piping run allows the stated overall length without strain.
