A pneumatic check valve from Grainger can allow air to flow through your air compressor in one direction and prevent compressed air from flowing back into it, helping compressors to keep certain parts pressurized and others depressurized. Find compact brass body valves, bronze valves, compressor in-tank valves, valves for tubing and more. Trust Grainger to offer pneumatic check valve options in a wide range of configurations.
