Norgren T73E-3AA-P1N Lockout Air Valve 3/8 Inch Npt

Product Description

The NORGREN T73E-3AA-P1N is a lockout air valve designed for compressed air isolation and energy control in pneumatic systems. It uses a slide actuator to shift between two positions, providing a positive mechanical lockout that helps meet OSHA lockout/tagout (LOTO) requirements. The valve features a 3/8 inch NPT threaded inlet with a Cv rating of 4.0 and a maximum working pressure of 250 psi. It handles flow up to 120 cubic feet per minute (CFM) and operates across a temperature range of -30 degrees F to 150 degrees F. Licensed industrial mechanics and pneumatic technicians install this valve as part of machine safeguarding and energy isolation systems.

This valve is suited for industrial and commercial pneumatic applications where a reliable, manually actuated lockout point is required on an air supply line. Typical installations include machinery isolation panels, compressed air distribution headers, and maintenance access points on production equipment. The 3/8 inch NPT threaded connection makes it compatible with standard pipe fittings used in industrial compressed air piping systems. It is appropriate for both new installations and retrofits where a mechanical lockout valve is being added to an existing pneumatic circuit.

Key Features

• Slide actuator provides positive 2-position mechanical lockout for LOTO-compliant energy isolation
• 3/8 inch NPT threaded inlet for direct connection to standard compressed air pipe fittings
• Cv rating of 4.0 with flow capacity up to 120 CFM
• Rated to 250 psi maximum working pressure
• Operating temperature range of -30 degrees F to 150 degrees F (-34 degrees C to 65 degrees C)
• Compact, threaded-connection design suitable for inline installation on air supply lines

Compatibility

Designed as a direct-fit lockout air valve for industrial pneumatic systems using 3/8 inch NPT threaded connections and compressed air supply pressures up to 250 psi.

Installation Notes

Installation should be performed by a qualified industrial mechanic or pneumatic systems technician. Depressurize and bleed down the air supply line fully before removing or installing any valve. Apply appropriate thread sealant to NPT connections in accordance with the system manufacturer guidelines and applicable codes. Verify that the installed valve is accessible and clearly labeled for lockout/tagout procedures per OSHA 29 CFR 1910.147.
