Norgren T70A3800 Quick Exhaust Valve 3/8 Inch Npt

Product Description

The NORGREN T70A3800 is a quick exhaust valve designed to accelerate the exhaust of air from pneumatic actuators, cylinders, and similar devices by venting directly at the point of use rather than routing exhaust back through the control valve. Constructed with a zinc body, this valve operates across a pressure range of 7 to 145 psi. The 3/8 inch NPT port connection makes it a straightforward fit into standard pneumatic plumbing. It is typically installed by industrial maintenance technicians, automation specialists, and fluid power professionals working on compressed air systems.

This quick exhaust valve is suited for use in industrial pneumatic circuits where faster actuator return speeds are needed. By exhausting air locally, it reduces cycle times on double-acting or spring-return cylinders. Typical applications include assembly automation, material handling equipment, and any pneumatic system where control valve exhaust porting creates a speed bottleneck. The 3/8 inch NPT sizing fits common mid-range actuator and cylinder port configurations found in light to medium industrial settings.

Key Features

• Quick exhaust function vents air directly at the actuator for faster cylinder response
• Operating pressure range of 7 to 145 psi covers a wide range of industrial pneumatic applications
• 3/8 inch NPT port connection for straightforward integration into standard pneumatic plumbing
• Zinc body construction provides durability in industrial environments
• Compact design installs close to the actuator to minimize exhaust path length

Compatibility

Designed as an OEM-style replacement or direct-install quick exhaust valve for pneumatic systems using 3/8 inch NPT porting operating within the 7 to 145 psi pressure range.

Installation Notes

Quick exhaust valves are installed by qualified fluid power technicians or industrial maintenance personnel familiar with compressed air systems. Depressurize and lock out the compressed air supply before servicing any pneumatic components. The valve should be mounted as close as possible to the actuator exhaust port to achieve maximum speed benefit. Verify that all NPT threaded connections are properly sealed with thread sealant rated for pneumatic service.
