Nibco NHAC0JF Gate Valve 3 in Flanged Iron 125 Class

Product Description

The NIBCO NHAC0JF is a non-rising stem gate valve built for full-bore isolation service in industrial and commercial piping systems. The valve features a cast iron body with a bolted bonnet and solid wedge disc, rated at Pressure Class 125. At 3 inches pipe size with flanged end connections, it is designed for use in larger-diameter pipelines where a reliable shutoff is required. The non-rising stem design keeps the stem height fixed during operation, making it well suited for installations with limited overhead clearance. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers for this class of valve.

This gate valve is used in a wide range of commercial and industrial applications including water distribution, HVAC hydronic systems, fire protection headers, and general industrial fluid handling. The flanged end connection simplifies installation and removal in systems where periodic maintenance access is needed. Pressure Class 125 ratings align with standard cast iron flanged fittings commonly used in building mechanical rooms, pump stations, and similar infrastructure environments.

Key Features

• Non-rising stem design suits installations with limited vertical clearance above the valve
• Bolted bonnet construction allows field repacking and maintenance without replacing the valve body
• Solid wedge disc provides positive shutoff across the full bore
• Flanged end connections rated to Pressure Class 125 for compatibility with standard cast iron flanged piping
• Cast iron body offers durability in water and compatible fluid services
• 3-inch pipe size supports high-flow applications in commercial and industrial piping runs

Compatibility

Designed as an OEM-style replacement or new installation gate valve for 3-inch flanged cast iron piping systems rated at Pressure Class 125.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes such as the IPC or ASME B16.1 flanged joint standards. Isolate and depressurize the system fully before removing or installing the valve. Flange bolt tightening should follow a cross-pattern sequence using appropriate gasket material rated for the service fluid and pressure class. Do not use the valve for throttling service; gate valves of this type are intended for full-open or full-closed operation only.
