Midland Industries 941140 Gate Valve 3 Inch Fpt Brass

Product Description

The MIDLAND INDUSTRIES 941140 is a 3-inch nominal quick-opening gate valve rated for 200 psi WOG (water, oil, gas) service. It features a brass body, brass stem, and brass disc with PTFE packing for reliable sealing across a range of fluid media. The valve connects via female pipe thread (FPT) on both ends and operates with a cast iron and brass handle for fast quarter-turn actuation. At 10.855 pounds, it is a heavy-duty valve suited for commercial and industrial plumbing, irrigation, and mechanical systems. Licensed plumbers and pipefitters install this valve in new construction and retrofit applications where a full-bore shutoff is required.

The 941140 is intended for use in residential and commercial plumbing systems, industrial fluid distribution, and mechanical piping where a 3-inch full-bore gate valve is specified. Its FPT x FPT end connections make it compatible with standard threaded pipe installations. The quick-opening handle design allows rapid shutoff or flow control without additional actuator hardware, making it practical for main line isolation, bypass lines, and service shutoffs in both above-grade and mechanical-room environments.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the supply line and drain the system before removing or installing the valve. Apply thread sealant or PTFE tape to male threads before making up the FPT connections. Do not overtighten threaded connections, as this can crack the valve body or distort the seat.
