Midland Industries 948142 Safety Exhaust Ball Valve 3/8in

Product Description

The MIDLAND INDUSTRIES 948142 is a vented safety exhaust ball valve designed for fluid control and pressure relief applications in plumbing, pneumatic, and industrial piping systems. Built with a brass body, brass ball, and brass stem, this full-port valve delivers a maximum working pressure of 400 psi WOG and 150 psi WSP. The 3/8-inch nominal FPT x FPT connections allow straightforward threaded installation into existing lines. A locking lever handle provides a positive shutoff and helps prevent accidental actuation in service environments. Licensed plumbers and pipefitters typically install this valve in commercial and light industrial applications where vented exhaust capability is required at the valve body.

This valve is suited for residential and commercial piping systems requiring a reliable inline shutoff with integrated vent function. The full-port design minimizes flow restriction, making it appropriate for systems where pressure drop must be kept low. The PTFE seat and PTFE packing provide chemical resistance and a durable, low-friction seal across the rated pressure range. The 1/4-18 thread size and compact body dimensions make it a practical fit in tight plumbing or pneumatic manifold installations.

Key Features

• Full-port design minimizes pressure drop across the valve
• Brass body, brass ball, and brass stem for corrosion resistance in fluid service
• PTFE seat and PTFE packing for chemical compatibility and low-friction sealing
• Locking lever handle prevents inadvertent operation during service
• Nickel-plated steel handle and stem nut trim for durability
• Rated 400 psi WOG and 150 psi WSP for broad application coverage

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/8-inch FPT threaded plumbing and pneumatic piping systems requiring a vented safety exhaust ball valve with full-port flow characteristics.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Depressurize and isolate the line fully before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male threads prior to making up connections, and avoid overtightening to prevent damage to the brass body. Verify system pressure does not exceed the rated WOG or WSP values before returning the line to service.
