Milwaukee Valve 115 Gate Valve

The Milwaukee Valve 115 is a bronze gate valve designed for controlling the flow of gas, oil, and water in plumbing and industrial piping systems. It features a 1-1/4 inch nominal size with a sweat solder connection for secure installation.

Sustained load performance

The solid bronze wedge and bronze seat provide reliable shut-off under continuous operating pressures up to 200 psi and steam pressures up to 125 psi. A non-rising bronze stem and screw-in bonnet maintain sealing integrity during prolonged service cycles.

Deciding specification

The valve offers a coefficient of volume (Cv) of 97, which determines the flow capacity through the 1-1/4 inch port. This rating confirms suitability for applications requiring this specific flow characteristic.

Questions about this item

Does the 125 psi steam rating mean the Milwaukee Valve 115 runs hot when it stays open all day?

The 125 psi steam rating is a pressure limit, not a temperature indicator. The valve body is bronze and has no moving parts that generate heat, so it does not warm up from continuous operation.

What pipe preparation do I need before I can sweat the 1-1/4 in connection on this gate valve?

You need 1-1/4 in copper tubing, flux and lead-free solder. Clean the tube end and the valve socket, apply flux, insert the tube fully, then heat the joint evenly until the solder flows around the socket.

Will the non-rising stem and solid bronze wedge of the 115 work with my older bronze-threaded fittings?

The valve uses a sweat connection, not threads, so it cannot screw directly onto threaded fittings. Use a bronze sweat-to-thread adapter if you must join it to existing threaded pipe.
