Norgren T73E-4AA-P1N Lockout Air Valve 1/2 Inch Npt

Product Description

The NORGREN T73E-4AA-P1N is a lockout air valve designed for pneumatic safety isolation in industrial and mechanical systems. It uses a slide actuator to shift between two positions, allowing a technician to physically lock out compressed air supply during maintenance or equipment servicing. The valve features a Cv rating of 8 and a maximum working pressure of 250 psi, with a flow capacity of 240 cubic feet per minute. It connects via 1/2 inch NPT threaded ports on both inlet and outlet. This valve is typically installed by industrial maintenance mechanics and HVAC or process equipment technicians who need a reliable, code-compliant energy isolation point.

The T73E-4AA-P1N is suited for compressed air systems in commercial, industrial, and light manufacturing environments where lockout/tagout (LOTO) procedures are required. It functions as an energy isolation device in pneumatic circuits, allowing safe de-energization of air-powered equipment before service. The 2-port, 2-position configuration makes it a straightforward shutoff and lockout solution on main supply lines or branch circuits serving pneumatic tools, actuators, or control systems.

Key Features

• Slide actuator provides tactile, positive actuation for lockout/tagout compliance
• Cv rating of 8 with 240 CFM flow capacity supports moderate to high-flow pneumatic circuits
• Rated to 250 psi maximum working pressure
• 1/2 inch NPT threaded inlet and outlet for standard pipe connection
• Operating temperature range: -30 degrees F to 150 degrees F (-34 degrees C to 65 degrees C)
• 2-port, 2-position valve design for simple on/off isolation

Compatibility

Designed as an OEM-style replacement or new-installation lockout air valve for pneumatic systems using 1/2 inch NPT threaded connections and operating within the stated pressure and temperature ratings.

Installation Notes

Installation should be performed by a qualified industrial mechanic or licensed technician in accordance with applicable OSHA lockout/tagout standards (29 CFR 1910.147) and local mechanical codes. De-pressurize the upstream air supply completely before installing or servicing this valve. Use appropriate thread sealant on NPT connections and verify all fittings are leak-free before returning the system to service. Do not exceed the 250 psi maximum working pressure rating.
