Legend Valve 116-122 Os and Y Gate Valve 2.5 Inch Flanged

Product Description

The LEGEND VALVE 116-122 is an outside stem and yoke (OS and Y) gate valve designed for full-bore isolation service in industrial and commercial piping systems. Built with a cast iron body and bolted bonnet, this valve handles 2.5-inch flanged connections at a 125 pressure class rating. The solid wedge disc provides reliable, low-leak shutoff in straight-line flow applications. At 48 pounds, the 116-122 is a heavy-duty valve suited for installation by licensed plumbers and pipefitters in mechanical rooms, boiler plants, fire protection piping, and process lines where positive visual stem indication of open or closed status is required.

This valve is intended for use in 2.5-inch flanged piping systems operating within 125-class pressure limits. Typical applications include commercial HVAC hydronic systems, industrial process lines, fire suppression headers, and water distribution mains where an OS and Y design is specified by code or insurance requirements. The rising stem design allows visual confirmation of valve position without requiring a position indicator accessory, making it a common choice in mechanical rooms and equipment rooms where quick status checks matter during service rounds.

Key Features

• Outside stem and yoke (OS and Y) design provides visible open and closed indication
• Cast iron body construction for durability in commercial and industrial service
• Bolted bonnet allows field repacking without removing the valve from the line
• Solid wedge disc delivers positive shutoff in full-bore gate valve service
• Flanged end connections rated to 125 pressure class for standard iron flange bolt patterns
• 2.5-inch pipe size fits common header and branch sizes in commercial mechanical systems

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 2.5-inch flanged cast iron piping systems operating at 125-class pressure ratings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including ASME B31.1 or B31.9 as relevant to the system. Depressurize and drain the line completely before removing the existing valve or making flanged connections. Verify flange bolt pattern, gasket rating, and flange face type before torquing fasteners. The valve should be installed in the fully open or fully closed position during initial pressure testing to confirm seat integrity.
