1" Bronze Gate Valve for Gas, Oil and Water

This Milwaukee Valve 1140 gate valve controls flow of gas, oil or water in a 1-inch line. The bronze body, bonnet, stem, wedge, seat and seal resist corrosion in typical plumbing and light-industrial service. A non-rising stem with a hand wheel allows local operation without vertical clearance changes. The valve is rated Class 150 for steam service.

Check Thread Type and Pressure Rating Before

Verify that your piping uses 1-inch female NPT threads to match the valve connections. Confirm the system operating pressure does not exceed 300 psi and that steam pressure stays at or below 150 psi. Ensure the media is compatible with bronze wetted parts and that a solid-wedge, non-rising-stem design suits your installation layout.

Thermal, Noise and Power Considerations in Normal

Bronze construction handles the temperature range implied by the 150 psi steam rating without external cooling. Manual wheel operation produces no electrical noise or power draw. The 54 Cv coefficient indicates moderate flow resistance, so pressure drop across the valve remains low in typical service.

Questions about this item

Does the valve include any gaskets or pipe fittings, or must I buy those separately?

The valve body, wheel handle, and NPT threaded ends are supplied. Flange gaskets, bolts, and any pipe nipples or adapters are not included and must be sourced separately.

Should I choose the Class 150 bronze model or a different pressure class for 150 psi steam service?

This model is rated 150 psi for steam and 300 psi for water, oil, or gas, so it meets the Class 150 steam requirement without needing a higher class.

What flow rate does the Cv 54 rating deliver in a typical 1-inch water line?

A Cv of 54 means the valve passes 54 US gallons per minute of water with a 1 psi pressure drop, so it adds minimal restriction to a 1-inch line.
