Legend Valve 116-421 Wafer Butterfly Valve 2 Inch Lever

Product Description

The LEGEND VALVE 116-421 is a manual wafer-style butterfly valve sized for 2-inch pipe, operated by a lever handle for quick quarter-turn shutoff. The body is cast iron, the disc is aluminum bronze, and the stem is stainless steel, combining corrosion resistance with mechanical durability. The seat is Buna-N elastomer, which provides a reliable seal across a broad range of general water and fluid service applications. This valve is a standard choice for licensed plumbers and pipefitters working on commercial and industrial piping systems where a compact, lightweight isolation valve is required between flanges.

The 116-421 is suited for wafer-style installation between ANSI-pattern flanges in 2-inch piping systems. Typical applications include commercial HVAC hydronic circuits, water distribution, and general industrial fluid handling where flow isolation or throttling is needed. The lever handle allows rapid manual actuation without tools, making it well suited for service valves and isolation points in accessible mechanical rooms or equipment skids.

Key Features

• Wafer body style installs between standard ANSI flanges without a full valve body flange, reducing face-to-face length and weight
• Lever handle provides quick quarter-turn operation for fast isolation
• Cast iron body offers strength and cost efficiency for standard fluid service environments
• Aluminum bronze disc resists corrosion in water and mildly aggressive fluid service
• Stainless steel stem resists corrosion and wear at the rotational point
• Buna-N seat delivers a resilient, drop-tight seal for general water service

Compatibility

Designed as an OEM-style wafer butterfly valve for 2-inch piping systems. Fits between standard ANSI-pattern flanges. Consult system documentation to confirm pressure rating, temperature range, and flange drilling pattern compatibility before installation.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local mechanical code requirements. Depressurize and drain the piping system completely before removing any existing valve or fitting. Center the wafer body between mating flanges and align the stem perpendicular to the pipe axis before tightening flange bolts in a cross pattern to ensure even seat compression. Verify the disc rotates fully to the open and closed positions without binding before returning the system to service.
