Midland Industries 940131 Brass Gate Valve 3/8 in Fpt 200 Psi

Product Description

The MIDLAND INDUSTRIES 940131 is a full-port brass gate valve designed for use in plumbing, gas, and oil distribution systems. It features a 3/8-inch nominal FPT x FPT connection and a working pressure rating of 200 psi WOG (water, oil, gas). The valve body is cast brass with a PTFE seat, cast brass stem, cast brass disc, and cast brass packing, offering durability across a wide service temperature range of 32 to 320 degrees F. A cast iron handle provides positive manual operation. The non-rising stem design keeps the installed height consistent during operation, making it suitable for installations with limited overhead clearance.

This valve is used in residential and light commercial piping systems where a reliable shutoff is needed for cold water, gas, or oil media. The full-port design minimizes flow restriction, which is important in low-pressure or flow-sensitive applications. Typical installations include branch line shutoffs, appliance isolation, and inline service valves. Licensed plumbers and gas fitters install this valve in compliance with applicable plumbing and mechanical codes.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the supply line and relieve any residual pressure before removing or installing the valve. Apply appropriate thread sealant or PTFE tape to male threads before making connections. Do not overtighten threaded fittings, and confirm all joints are leak-free under system pressure before returning the line to service.
