Legend Valve 104-503 Bronze Gate Valve 1/2 Inch Threaded

Product Description

The LEGEND VALVE 104-503 is a 1/2-inch bronze gate valve designed for full-flow shutoff in residential and light commercial plumbing systems. It features a non-rising stem design, which keeps the stem contained within the valve body during operation — a practical advantage in tight mechanical spaces where vertical clearance is limited. The body is cast bronze with a solid wedge disc and a screw-in bonnet for straightforward field service. This valve is installed by licensed plumbers and pipefitters working on water distribution, hydronic, and general-purpose piping systems.

This valve suits 1/2-inch threaded pipe connections in applications such as domestic water supply lines, boiler feed circuits, and zone isolation in hydronic heating systems. The threaded end connection (NPT-style) allows for direct installation into existing threaded pipe runs without special tooling or adapters. It is appropriate for residential retrofits and new construction where a compact, reliable shutoff valve is required at branch or service points.

Key Features

• Non-rising stem keeps overall installed height fixed during valve operation
• Bronze body provides corrosion resistance in water service applications
• Solid wedge disc delivers reliable full-close shutoff
• Screw-in bonnet allows field access to internal components without removing the valve from the line
• 1/2-inch threaded end connection fits standard NPT pipe threads

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 1/2-inch threaded pipe systems in residential and light commercial plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before removing any existing valve or making threaded connections. Apply thread sealant or PTFE tape to male threads before assembly and tighten to a snug, leak-free fit — do not overtighten bronze-body valves. Gate valves are intended for full-open or full-closed service and should not be used to throttle flow.
