Bronze gate valve for fluid control

The Milwaukee Valve 1140 is a 1-1/4 inch bronze gate valve rated for 300 psi operating pressure and 150 psi steam service. It handles gas, oil and water with a solid bronze wedge and bronze seat for durable sealing. A non-rising bronze stem and wheel handle provide manual operation in commercial or industrial piping systems.

Check thread type and pressure requirements

Verify that your piping uses 1-1/4 inch female NPT connections to match the valve ends. Confirm the system operating pressure does not exceed 300 psi and steam pressure stays within 150 psi. The screw-in bonnet and non-rising stem need enough clearance above the pipeline for the wheel handle to turn freely.

Suits installers needing bronze NPT gate valves

This valve fits plumbers and maintenance crews who require a bronze body with NPT threads for gas, oil or water lines up to 300 psi. It is not for systems that need flanged connections, rising-stem visibility or higher pressure ratings. Buyers who want more connection options or different body materials should look at other valve types.

Questions about this item

What comes with the 1140 gate valve and do I need to buy pipe fittings separately?

The valve body includes a bronze wheel handle and solid bronze wedge; NPT pipe fittings and thread sealant are not included and must be purchased separately.

Should I choose the 300 psi or 150 psi rating for my water line?

The 300 psi rating covers water, oil and gas service; the 150 psi figure applies only to steam, so select based on the fluid you will carry.

What does the Cv 97 value mean when the valve is installed in my plumbing?

A Cv of 97 means the valve will pass 97 US gallons per minute of water at a 1 psi pressure drop when fully open.
