Legend Valve 116-124 Os Y Gate Valve 4 Inch Flanged Cast Iron

Product Description

The LEGEND VALVE 116-124 is a 4-inch outside stem and yoke (OS and Y) gate valve designed for full-bore isolation service in industrial and commercial piping systems. The cast iron body pairs with a bolted bonnet and solid wedge disc to provide reliable shutoff in low-pressure fluid service. Flanged end connections allow direct bolt-up to standard 125-class flanged piping. At 103 pounds, this is a heavy-duty valve intended for permanent installation in mechanical rooms, pump stations, and process piping headers. Licensed pipefitters and industrial mechanical contractors are the primary installers.

This valve is suited for water, low-pressure steam, and compatible fluid service in commercial or light industrial applications where a 4-inch flanged connection and OS and Y stem configuration are required. The OS and Y design provides a visual open or closed indicator and is required by many fire protection and mechanical codes in specific service locations. The solid wedge disc delivers dependable seating in straight-run piping where flow direction does not reverse under pressure surges.

Key Features

• Outside stem and yoke (OS and Y) design gives visual valve position indication at a glance
• Cast iron body rated to 125 pressure class for compatibility with standard flanged piping systems
• Solid wedge disc provides positive, full-bore shutoff with minimal turbulence in the open position
• Bolted bonnet construction allows field repacking without removing the valve from the line
• 4-inch flanged end connections bolt directly to 125-class flat-face or raised-face flanges
• Heavy-duty build at 103 pounds suits permanent mechanical room and pump station installations

Compatibility

Designed as an OEM-style flanged gate valve for 4-inch, 125-class cast iron flanged piping systems typical in commercial and light industrial mechanical applications.

Installation Notes

Installation should be performed by a licensed pipefitter or plumbing contractor in accordance with applicable mechanical and plumbing codes such as the IPC or ASME B31.1. Isolate and fully depressurize the line and drain fluid before removing any existing valve or breaking a flanged joint. Verify flange face type and bolt-circle dimensions match the mating flanges before installation, and use appropriate gaskets rated for the service fluid and pressure. Do not exceed the rated pressure class of 125 for this valve body.
