Legend Valve 116-407 Wafer Butterfly Valve 8 Inch

Product Description

The LEGEND VALVE 116-407 is a manual wafer-style butterfly valve sized for 8-inch pipe, operated by a lever handle. It is designed for on/off flow control in commercial and industrial piping systems. The body is cast iron, the disc is aluminum bronze, and the stem is stainless steel, making this valve suited for demanding fluid-handling applications. The seat is EPDM (Ethylene Propylene Diene Monomer), which provides a reliable seal in water and many chemical service lines. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this valve type.

This valve is used in commercial HVAC hydronic systems, water distribution, and industrial process piping where a compact, face-to-face wafer design is required. The wafer configuration allows the valve to fit between standard pipe flanges without a full flanged body, saving installation space. It is appropriate for both new construction and retrofit projects on 8-inch pipe runs where manual isolation or throttling is needed.

Key Features

• Wafer-style body fits between standard pipe flanges for a compact installation footprint
• Cast iron body provides structural durability in commercial and industrial service
• Aluminum bronze disc resists corrosion in water and general fluid service
• Stainless steel stem offers corrosion resistance and long service life
• EPDM seat material is compatible with water, steam condensate, and many mild chemical services
• Lever handle allows quick manual actuation for on/off flow control

Compatibility

Designed as an OEM-style replacement or new-installation wafer butterfly valve for 8-inch pipe systems using standard flange bolt patterns in commercial plumbing and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and ASME B31.1 or B31.9 piping standards. Isolate and depressurize the pipe segment fully before mounting the valve between flanges. Confirm flange bolt circle and gasket compatibility before installation. Do not overtighten flange bolts unevenly, as this can distort the valve seat and cause leakage.
