Gate Valve for Water Systems
This Milwaukee Valve UP149 is a 1/2-inch gate valve designed for water media in residential or light commercial plumbing. The bronze body and solid bronze wedge provide durable shut-off control for supply lines. It suits installers needing a reliable solder-connection valve for new or replacement work. The rising stem design allows visual confirmation of the open or closed position.
Bronze Construction and Solder Connection
The valve body, bonnet, wedge, seat and seal are all bronze with a brass stem, offering corrosion resistance for potable water applications. A screw-in bonnet style secures the internal components while allowing maintenance access if required. The sweat connection on the inlet side requires soldering to copper pipe, creating a permanent, leak-resistant joint. The wheel handle provides mechanical advantage for operating the valve against line pressure.
Pressure Rating and Flow Capacity
Rated for a maximum operating pressure of 300 psi, the valve handles typical municipal and well-pump supply pressures. The coefficient of volume (Cv) of 17.6 indicates the flow capacity when the gate is fully open, helping engineers size the valve for the required system flow rate. Steam service is not applicable for this model. The rising stem moves linearly, so clearance above the valve is needed for full operation.

Questions about this item
What pressure does the 1/2 inch solder gate valve handle in practice?
The bronze body is rated for 300 psi maximum operating pressure with water media, and the solid bronze wedge seats against bronze seats for a tight shut-off.
What pipe size and connection type does the UP149 need to fit?
It fits 1/2 inch copper tubing using a sweat solder joint on the inlet side, with a bronze body and screw-in bonnet that match standard residential plumbing dimensions.
How is this rising-stem gate valve installed, and what step is often missed?
Clean and flux the copper tube ends, slide the valve onto the pipes, solder the sweat connections while the valve is fully open to protect the bronze seats, then operate the wheel handle to verify smooth stem travel.
