Norgren T74E-6AA-P1N Lockout Air Valve 3/4 Inch Npt

Product Description

The NORGREN T74E-6AA-P1N is a 3-port, 2-position lockout air valve designed for industrial pneumatic systems where positive isolation and energy control are required. It features a slide actuator that allows technicians to manually lock the valve in the off position, supporting LOTO (lockout/tagout) procedures. The valve accepts 3/4-inch NPT threaded connections at both inlet and outlet and is rated for a maximum working pressure of 250 psi with a Cv rating of 7.7, supporting flow up to 231 cubic feet per minute. It is suited for use by pneumatic system technicians and maintenance professionals working in industrial and commercial facilities.

This valve is installed in compressed air supply lines where isolation of downstream equipment is required before maintenance or servicing. The slide actuator provides a clear visual indication of valve state, making it a practical choice for machine guarding, air preparation panels, and point-of-use lockout stations. It is compatible with standard NPT-threaded piping and tubing systems commonly found in manufacturing, processing, and mechanical service environments.

Key Features

• Slide actuator enables manual lockout for LOTO-compliant isolation procedures
• 3-port, 2-position valve design for direct inline installation
• 3/4-inch NPT threaded inlet and outlet for standard pipe connections
• Cv rating of 7.7 with airflow capacity of 231 CFM
• Maximum working pressure of 250 psi for demanding pneumatic circuits
• Operating temperature range of -30 degrees F to 150 degrees F

Compatibility

Designed as an OEM-style replacement or direct installation component for industrial compressed air systems using 3/4-inch NPT threaded connections and requiring lockout-capable 3-port valve assemblies.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance professional. Depressurize and fully isolate the compressed air supply before removing any existing valve or fitting. Follow applicable OSHA lockout/tagout regulations and facility energy control procedures when servicing connected equipment. Apply thread sealant appropriate for pneumatic service on all NPT connections and verify for leaks after pressurizing the system.
