Professional plumbing control
The Milwaukee Valve UP105 is a 1 1/2 inch bronze gate valve designed for water supply lines in residential and commercial plumbing systems. Its NPT female threads allow direct connection to standard threaded pipe without additional adapters. The non-rising stem keeps the handle at a fixed height, making it suitable for installations where vertical clearance is limited.
Bronze construction with screw-in bonnet
The body, bonnet, wedge and seat are all cast bronze for corrosion resistance in potable water applications. A screw-in bonnet simplifies maintenance by allowing access to internal components without removing the valve from the pipeline. Brass stem material resists galling during repeated operation, while the solid bronze wedge provides a positive shut-off when fully seated.
300 psi pressure rating limits use
Rated for a maximum operating pressure of 300 psi, this valve suits typical municipal and pumped water systems but is not rated for steam service. The 135 Cv coefficient indicates high flow capacity with minimal restriction when fully open. Buyers needing steam-rated isolation or higher pressure classes must select a different valve design.

Questions about this item
What pressure does the NPT connection on the UP105 gate valve handle in practice?
The bronze body and NPT threads are rated for 300 psi maximum operating pressure with water media.
What pipe size and thread type does the 1 1/2 inch valve need to mount?
It requires a 1 1/2 inch female NPT threaded pipe connection on each side for installation.
How is the screw-in bonnet installed, and what step is often missed?
Thread the bronze bonnet into the body by hand, then tighten with a wrench on the bonnet flats; the step often missed is ensuring the non-rising brass stem and solid bronze wedge are fully seated before final bonnet torque.
