Norgren C20GL0400 Non-return Valve 1/4 in Tube 150 Psi

Product Description

The NORGREN C20GL0400 is a non-return (check) valve designed for compressed air and pneumatic flow control applications. It allows flow in one direction only, preventing backflow in the line. The valve features a 1/4-inch tube outside diameter connection and a maximum working pressure rating of 150 psi. The plastic body construction keeps weight minimal at 0.02 pounds, making it well suited for lightweight pneumatic assemblies. Licensed HVAC technicians, pneumatic system technicians, and industrial maintenance professionals typically install this type of fitting in compressed air distribution lines, control circuits, and automated equipment.

This valve is used in pneumatic control systems where backflow prevention is required. Common applications include compressed air supply lines, actuator circuits, and instrumentation tubing runs in both light commercial and industrial settings. The tube-style connection accepts 1/4-inch OD tubing for quick, tool-free installation into push-to-connect or compression-style pneumatic circuits. Its compact footprint — 0.42 inches wide and 0.78 inches tall — allows installation in tight panel or manifold configurations.

Key Features

• Non-return (check) valve function prevents backflow in pneumatic lines
• 1/4-inch tube OD connection for compatibility with standard pneumatic tubing
• 150 psi maximum working pressure rating
• Plastic body construction for lightweight, corrosion-resistant performance
• Compact dimensions: 0.78 inches height, 0.42 inches width and length
• Low installed weight of 0.02 pounds suitable for space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or new-installation non-return valve for pneumatic systems using 1/4-inch OD tubing at working pressures up to 150 psi.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system safety procedures. Always depressurize and lock out the air supply before removing or installing any inline valve. Verify that tubing OD matches the valve connection size before assembly, and confirm that system operating pressure does not exceed the 150 psi maximum working pressure rating of this valve.
