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.
