Legend Valve 116-624 Lug Butterfly Valve 4 Inch

Product Description

The LEGEND VALVE 116-624 is a manual lug-style butterfly valve designed for 4-inch pipe systems. It controls flow in plumbing, HVAC, and industrial piping applications using a quarter-turn lever handle for quick shutoff or throttling. The cast iron body provides structural durability in demanding service environments, while the aluminum bronze disc offers corrosion resistance in water and mild chemical service. The stainless steel stem resists wear and corrosion at the pivot point. The Buna-N seat delivers a reliable elastomeric seal for general-purpose fluid handling. Licensed plumbers and pipefitters are the primary installers for this valve in commercial and industrial systems.

This valve is suited for commercial plumbing, HVAC hydronic systems, water distribution, and light industrial piping where a lug-body butterfly valve is required at a 4-inch pipe size. The lug pattern allows the valve to be installed as an end-of-line valve or between flanges without requiring a companion flange on the downstream side, which makes it practical for dead-end service and system sectioning. The lever handle enables fast manual operation without additional actuator hardware.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Isolate and depressurize the system and drain the line before removing any existing valve or installing this valve. Confirm flange bolt pattern and pressure rating compatibility with the mating flanges before installation. Do not exceed the rated service pressure or temperature for the Buna-N seat material in the intended application.
