1/2" Bronze Gate Valve Class 300

This Milwaukee Valve 1186 gate valve controls flow of gas, oil, or water in piping systems rated for up to 1,000 psi. The bronze body and stainless-steel seats handle steam pressures up to 300 psi. A non-rising bronze stem and solid bronze wedge provide reliable shut-off with a wheel handle.

Installers needing 1/2" FNPT connections

Suits projects where a union-bonnet bronze valve meets the pressure and media requirements. Not for applications requiring flanged ends, rising-stem indication, or larger nominal sizes. Builders needing different connection types or higher flow coefficients should look at other valve configurations.

1,000 psi cold working pressure rating

The decisive specification is the 1,000 psi maximum operating pressure for water, oil, and gas service. Steam service is limited to 300 psi. Verify that your system design pressure falls within these limits before selecting this valve.

Questions about this item

What size NPT threads does the 1186 valve need for mounting?

The valve has a 1/2 inch female NPT connection on each side for direct pipe threading.

How is the wheel handle installed on the non-rising stem, and what step is often missed?

The wheel handle mounts on the bronze non-rising stem; the step often missed is tightening the packing nut after handle installation to prevent stem leaks.

When will the stainless steel seats or bronze seals need replacement?

Inspect the stainless steel seats and bronze seals during routine maintenance; replace them if leakage appears or after prolonged exposure to 300 psi steam or 1000 psi operating pressure.
