Pneumatic Check Valves

Pneumatic check valves (also known as non-return valves) are installed into air compressor discharge lines for air to flow in one direction & prevent backflow of compressed air. CDI Control Devices pneumatic valves feature glass-filled PTFE poppet for high density & resistance to high temperatures and a positive seating fluoropolymer disc that provides a maximum airflow of 220 scfm. We also offer Conrader brass in-line check valves that have a cracking pressure of less than 1 psi and can withstand a maximum operating temperature of 450 deg F whilst providing airflows up to 95 scfm. Choose from a wide variety of CDI Control Devices and Conrader pneumatic valves in vertical, horizontal & in-tank mounting variants on Raptor Supplies.
