1-1/4" Class 300 Bronze Gate Valve

The Milwaukee Valve 1186 is a bronze gate valve designed for controlling flow in piping systems carrying gas, oil or water. Its 1-1/4 inch female NPT connections suit standard threaded pipework in commercial and industrial installations.

Sustained pressure and steam rating

The valve handles a maximum operating pressure of 1,000 psi and a steam rating of 300 psi, with a bronze body, bonnet, stem and solid wedge that resist deformation under continuous load. A union bonnet and stainless-steel seats maintain sealing integrity over repeated cycles.

Cv 97 flow coefficient

A coefficient of volume of 97 determines the flow capacity at a given pressure drop, making this the decisive figure for sizing the valve to the system. Buyers needing a higher or lower Cv must select a different model.

Questions about this item

Will the bronze body and non-rising stem run hot or make noise under continuous 1,000 psi water service?

Bronze body and bronze stem run cool with no moving parts that generate noise; the solid bronze wedge and stainless steel seats handle 1,000 psi cold water pressure continuously without heat buildup or vibration.

What piping must I already have to install this 1-1/4" FNPT gate valve?

You need 1-1/4" male NPT threads on both pipe ends; the valve's female NPT connections thread directly onto them with no flanges, solder joints or adapters required.

Can I keep my existing bronze trim and stainless seats when adding this Class 300 valve to an older steam line?

Yes — the bronze wedge, bronze stem, bronze seals and stainless steel seats match traditional bronze trim, so the valve integrates with older bronze-bodied steam piping rated for 300 psi steam.
