Legend Valve 116-423 Wafer Butterfly Valve 3 Inch

Product Description

The LEGEND VALVE 116-423 is a manual wafer-style butterfly valve designed for flow control in piping systems. It features a cast iron body, an aluminum bronze disc, a stainless steel stem, and a Buna-N seat. The lever handle provides quick quarter-turn operation for shutoff or throttling service. At 11 pounds, this is a robust, full-bodied valve suited for commercial and industrial piping applications. Licensed plumbers and pipefitters typically install this valve in hydronic, water distribution, and general-service liquid lines where a compact wafer profile is required to fit between standard pipe flanges.

This valve fits 3-inch pipe and installs between mating flanges without the need for flange faces on the valve body itself, keeping the overall face-to-face dimension tight. The wafer configuration is common in mechanical rooms, pump stations, and process piping where space between flanges is limited. The lever handle is appropriate for applications requiring manual, on-off or throttling control without a gear operator or actuator.

Key Features

• Wafer-style body fits between standard pipe flanges for compact installation
• Cast iron body provides durability in commercial and industrial service
• Aluminum bronze disc offers corrosion resistance in water and mild fluid service
• Stainless steel stem resists corrosion and wear over repeated cycles
• Buna-N seat material compatible with water and general-service liquids
• Lever handle delivers fast quarter-turn shutoff without additional tooling

Compatibility

Designed as an OEM-style wafer butterfly valve for 3-inch pipe systems using standard flange bolt patterns in commercial and industrial plumbing or hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME piping standards. Isolate and depressurize the system and drain the line before removing the existing valve or installing this unit. Align the valve carefully between mating flanges and verify the disc is in the fully closed position before torquing flange bolts to prevent seat damage. Do not use this valve to support piping loads; install adequate pipe supports on each side of the valve.
