Macomb Group Approved 12001503FEGV 12 in Class 150 Gate Valve

Product Description

The MACOMB GROUP APPROVED 12001503FEGV is a 12-inch, Class 150 flanged gate valve designed for industrial pipeline service. Built with a carbon steel body conforming to ASTM A216 Grade WCB, this valve is rated to 285 PSIG at temperatures from -20 to 100 degrees F, with a full temperature range of -20 to 800 degrees F. The handwheel operator uses a malleable iron handle and a stainless steel stem (ASTM A182 Grade F6A), giving it durable, reliable manual actuation. A licensed pipefitter or industrial valve technician is the typical installer for a fitting of this size and pressure class.

This gate valve is suited to heavy industrial and commercial piping systems where a full-bore, low-restriction shutoff is required. The flanged end connections follow ASME B16.5 and ASME B16.34 standards, making it compatible with standard Class 150 flanged piping assemblies in oil, gas, steam, water, and process fluid applications. The 14-inch face-to-face width and 55.6-inch overall height from inlet centerline to top of handle should be confirmed against available installation clearance before ordering.

Key Features

• 12-inch nominal bore with full-bore gate design and a flow coefficient (Cv) of 10000 for minimal pressure drop
• Class 150 pressure rating at 285 PSIG from -20 to 100 degrees F
• Carbon steel body (ASTM A216 Grade WCB) rated for service up to 800 degrees F
• Stainless steel stem (ASTM A182 Grade F6A) for corrosion resistance and long service life
• Flanged end connections meeting ASME B16.5, B16.10, B16.25, and B16.34 standards
• Compliant with API 600 for industrial gate valve construction requirements

Compatibility

Designed as a Class 150 flanged gate valve replacement or new installation fitting for standard ASME B16.5 Class 150 flanged piping systems in industrial and commercial process applications.

Installation Notes

Installation of a 12-inch industrial gate valve of this pressure class should be performed by a licensed pipefitter or qualified industrial piping technician. Isolate and depressurize the pipeline fully before removing any existing valve or breaking any flanged connection. Confirm flange bolt patterns, gasket dimensions, and pipe alignment to ASME B16.5 Class 150 requirements before installation. Verify that the 55.6-inch handle clearance height and 19.75-inch handwheel diameter are accommodated in the installation space.
