Gate valve for gas oil water

The Milwaukee Valve 1140 is a bronze gate valve designed for gas, oil and water service. Its 1 1/2 inch NPT female connection suits residential and light commercial plumbing systems. The solid bronze wedge and bronze seat provide a tight shut-off for on-off control.

Sustained pressure rating

The valve withstands a maximum operating pressure of 300 psi and a maximum steam pressure of 150 psi. A coefficient of volume of 135 indicates high flow capacity with minimal restriction. The non-rising stem and screw-in bonnet maintain seal integrity under continuous service conditions.

Bronze construction and NPT threading

All wetted parts including body, bonnet, stem, wedge, seat and seal are bronze for corrosion resistance. The screw-in bonnet allows straightforward maintenance without special tools. Female NPT threads enable direct connection to standard pipe fittings without adapters.

Questions about this item

How much heat does the 1140 gate valve generate when it runs all day?

The valve has no moving electrical parts, so it produces no measurable heat during continuous operation.

What piping must I already have to install this 1 1/2 inch NPT bronze valve?

You need a 1 1/2 inch female NPT threaded pipe on each side to match the valve connections.

Will the 300 psi rated bronze valve work with my existing Class 150 steel flanges?

This model uses NPT threads, not flanges, so it cannot bolt directly to Class 150 flanged pipework.
