             Check Valves
             DK Series Check Valves are Built for Integral
             Circuits, Offer Easy Installation and Removal.
             DK Series check valves are designed for use in integral cir-
             cuits where the valve is installed in the housing of another
             component. Because the valve is easily installed and
             removed, circuit troubleshooting is greatly simplified.
             Design engineers recommend the DK Series for use with
             integral circuits because they are dependable and efficient.
             Features:
             1.  All steel construction with a zinc plated exterior
                no internal seals or gaskets to wear out.
             2.  "Drop-in" design eliminates threaded connections.
             3.  One-piece body eliminates threads and seals that may
                be potential failure or leakage points.
             4.  Valve seats resist damage from shocks, surges and
                contamination.
             5.  Poppet spring is isolated from the liquid flow stream,
                minimizing turbulence.                                        HOUSING
             6.  Poppet is heat treated to help prevent damage from
                shocks, surges and galling.
