DT Series Check Valves

Parker DT Series check or one-way valves are installed in pipelines to prevent backflow and ensure efficient operation. They feature all steel construction to resist corrosion and a one piece body design to eliminate threads & seals, thus preventing leakage and allowing smooth flow by isolating the poppet springs from the streams. They have chromium 6 free plating on exterior parts to increase hardness & durability, and UN, UNF & UNS inlet ports for improved fatigue resistance. Choose from a wide range of these valves, available in operating pressure up to 4500 psi.

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.

We are here to help!
