2-inch Bronze Swing Y Check Valve

This Milwaukee Valve 515Y is a bronze-bodied check valve with a Y-pattern swing mechanism designed for horizontal or vertical installation. It handles water up to 300 psi at 150 degrees F and steam up to 150 psi WSP across a temperature range of -20 to 425 degrees F. The FNPT x FNPT connections accept 2-inch pipe and the valve delivers a full-flow capacity of 131 gpm with a cracking pressure of .5 psi.

For Plumbers and Hydronic Installers Needing

This valve suits contractors who need a bronze swing check that can be mounted in either orientation and will operate reliably from sub-freezing up to high-temperature steam service. It is not for systems requiring a soft-seat seal for zero-leakage shutoff or for piping smaller than 2-inch nominal size.

300 psi Water / 150 psi Steam Rating Decides Fit

The maximum pressure ratings of 300 psi for water at 150 degrees F and 150 psi WSP for steam are the primary specifications that determine whether this 515Y matches the design pressure of the intended piping system.

Questions about this item

What cracking pressure does the 515Y valve require to open?

The valve begins to open at 0.5 psi cracking pressure, allowing flow in the forward direction while preventing backflow.

What pipe size and thread type does the 515Y valve connect to?

It fits 2 inch FNPT female threaded connections on both inlet and outlet, requiring matching male NPT pipe ends.

How should the 515Y valve be oriented during installation?

Install with the flow arrow pointing downstream; the valve works in horizontal or vertical runs, but the hinge pin must stay level in horizontal lines so the disc swings freely.
