Valve for gas, oil and water systems

The Milwaukee Valve 105 gate valve handles gas, oil and water in a bronze body rated for 200 psi operating pressure and 125 psi steam pressure. Its 1-1/4 inch female NPT connections suit residential and light-commercial piping where a solid bronze wedge and bronze seat provide tight shut-off. The non-rising stem and wheel handle allow operation in confined spaces without stem travel.

Bronze construction limits heat and noise

All pressure-bearing parts — body, bonnet, stem, wedge, seat and seal — are bronze, so the valve does not generate vibration or noise under normal flow. The screw-in bonnet and non-rising stem keep the envelope compact, reducing thermal expansion stress on adjacent pipework. Pressure drop remains predictable with a Cv of 97 across the full 200 psi range.

Wheel handle and NPT threads simplify installation

The wheel handle gives direct mechanical leverage without needing actuators or power. Female NPT threads on the 1-1/4 inch port accept standard pipe nipples, eliminating adapters. No electrical connections, software or external power are required, so the valve works in locations where powered actuators are impractical.

Questions about this item

How do I install this 1-1/4" NPT bronze gate valve and what step is often missed?

Thread the female NPT ends onto matching male pipe threads using pipe sealant rated for 200 psi water, oil or gas service; the step often missed is tightening the screw-in bonnet joint after the body is in line to prevent leakage at the bonnet-to-body seal.

What maintenance or replacement will this solid-wedge bronze gate valve need over time?

The bronze stem, solid wedge and bronze seats are designed for long service; periodic operation prevents seizing, and if seat wear eventually reduces the Cv below the rated 97 the wedge and seat faces can be lapped or the valve replaced.

What is the first pressure limit reached during sustained steam service at the rated 125 psi?

The valve carries a 125 psi maximum steam rating and a 200 psi maximum non-shock cold water, oil or gas rating; in sustained steam use the 125 psi steam limit is the governing constraint.
