3/8" Bronze Y Swing Check Valve

The Milwaukee Valve 507 uses a Y-pattern bronze body with a swing-disc mechanism to allow flow in one direction while preventing back-flow. It connects via FNPT threads on both ends and suits horizontal or vertical mounting. Rated for 600 psi water pressure at 150 Degrees F and 300 psi saturated steam, it operates between -20 and 550 Degrees F.

Sustained-pressure reliability

The bronze body and bronze seat maintain sealing integrity across the full temperature range without soft-seat degradation. A cracking pressure of .750 to 1.000 psi keeps the disc closed under low-head conditions yet opens fully for a 6 gpm flow capacity. Chrome-cobalt seal material resists wear during continuous cycling in hot-water or steam lines.

Replaces worn swing-checks in small-bore piping

This valve upgrades installations where a failed disc, corroded seat or leaking body compromise system isolation. The 2.25 in overall length fits existing 3/8" FNPT connections without re-piping. It is not suited for lines requiring a lift-check profile, soft-seat bubble-tight shut-off or larger pipe diameters.
