Nibco ng1040f 3 Inch Fire Safe Flanged Ball Valve CL150

Product Description

The NIBCO ng1040f is a 3-inch carbon steel fire safe flanged ball valve designed for demanding industrial and commercial piping systems. It features a reinforced PTFE seat and 316 stainless steel ball trim, providing reliable shutoff performance in both standard and fire-safe service conditions. The valve operates with a lever handle for quick quarter-turn actuation. Rated at Class 150 with a 285 CWP working pressure, it meets API 607, API 608, and API 598 standards, making it a code-compliant choice for licensed pipefitters and mechanical contractors handling process, HVAC, and fire-safe fluid control applications.

This valve is suited for industrial process piping, commercial HVAC systems, and other applications requiring a flanged end connection with fire-safe certification. The carbon steel body construction makes it appropriate for non-corrosive fluid service at elevated pressures. The flanged end configuration conforms to standard bolt patterns, allowing straightforward installation into existing piping infrastructure. Mechanical contractors and licensed pipefitters typically specify this valve where fire-safe shutoff capability and pressure class compliance are both required by code or project specification.

Key Features

• Fire safe design certified to API 607 and API 608
• 316 stainless steel ball trim for corrosion resistance in the flow path
• Reinforced PTFE seat for tight shutoff and extended service life
• Lever handle for fast quarter-turn open and close operation
• Class 150 flanged ends rated to 285 CWP
• API 598 tested for shell, seat, and backseat integrity

Compatibility

Designed as an OEM-style flanged ball valve replacement for Class 150 carbon steel piping systems requiring fire-safe certification per API 607 and API 608.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical and fire protection codes. Depressurize and drain the piping system fully before removing or installing this valve. Flange gaskets and bolting should be selected and torqued per the applicable piping specification and ASME B16.5 requirements for Class 150 connections. Confirm valve orientation and flow direction before final bolt-up and pressure testing.
