Legend Valve 104-511 Bronze Gate Valve 4 Inch Threaded

Product Description

The LEGEND VALVE 104-511 is a 4-inch bronze gate valve with a non-rising stem design, built for full-bore shut-off service in commercial and industrial piping systems. The threaded end connection allows direct installation into existing pipe without welding or flanging equipment. A screw-in bonnet provides a compact, leak-resistant seal that holds up under repeated open-close cycles. The solid wedge disc delivers positive shut-off with minimal leakage when fully seated. At 17.75 pounds, this is a substantial valve suited for mainline isolation in water distribution, HVAC hydronic systems, and general plumbing service.

This valve is designed for use in applications where full-flow isolation is required and where headroom is limited, making the non-rising stem design the preferred choice. Typical installations include main water service lines, building mechanical rooms, boiler rooms, and process piping where a threaded 4-inch connection is already present. Licensed plumbers and pipefitters are the primary installers on commercial jobs. The bronze body resists dezincification and corrosion in potable water and HVAC hydronic service.

Key Features

• Non-rising stem keeps overall valve height compact, ideal for tight mechanical spaces
• Bronze body construction for corrosion resistance in water and hydronic service
• Threaded end connection for direct pipe installation without welding
• Solid wedge disc provides positive, low-leakage shut-off when fully seated
• Screw-in bonnet design for a secure, serviceable seal

Compatibility

Designed as an OEM-style replacement or new-installation bronze gate valve for 4-inch threaded pipe systems in commercial plumbing, HVAC hydronic, and general industrial service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IPC guidelines. Shut off and depressurize the system completely before removing any existing valve or making new connections. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not use this valve in partially open positions for flow throttling, as gate valves are designed for full-open or full-closed service only.
