Milwaukee Valve 1186 Gate Valve

The Milwaukee Valve 1186 is a bronze gate valve designed for controlling the flow of gas, oil, or water in piping systems. It features a 1-1/2 inch nominal size with female NPT connections and a Class 300 rating for steam service up to 300 psi. The non-rising stem and solid wedge design provide reliable shut-off capability. This new valve suits industrial and commercial plumbing installations requiring durable bronze construction.

Compatibility Check Before Ordering

Verify that your piping system uses 1-1/2 inch female NPT threads to match the valve connections. Confirm the operating pressure does not exceed 1,000 psi for general media or 300 psi for steam applications. Ensure the bronze body and stainless steel seat materials are compatible with the specific fluid being controlled. The union bonnet style requires adequate space for installation and future maintenance access.

Build Integration and Clearances

The valve's bronze construction with stainless steel seats resists corrosion in gas, oil, and water service. A 135 Cv rating indicates high flow capacity when the solid wedge is fully open. The wheel handle allows manual operation without requiring actuator mounting space. The union bonnet design permits inline maintenance without removing the valve from the pipeline. The non-rising stem keeps the overall height constant during operation.

Questions about this item

Does the Milwaukee Valve 1186 come with pipe sealant or flanges, or must those be purchased separately?

The valve is supplied as a single bronze body with a wheel handle; pipe sealant, flanges and mating fittings are not included and must be sourced separately.

Should I select the Class 300 FNPT version or a different pressure class for 300 psi steam service?

The Class 300 rating matches the 300 psi steam limit stated for this valve, so the listed version is the correct choice for that duty.

What does the Cv 135 figure mean for flow once the valve is installed in a 1-1/2 inch line?

A Cv of 135 indicates the valve will pass 135 US gallons per minute of water with a 1 psi pressure drop, giving high capacity for gas, oil or water systems.
