Double Valves
    Double Valves can be installed with either or both of the traditional standing and traveling valves in a rod pump. This additional valve is installed in series with the normal valve and provides a second fluid check valve in the pumping system. The application for Double Valves is whenever the pump experiences valve seat cutting from high pressure fluid leaking past particulates trapped on the sealing face between the valve ball and seat. A second valve in series with the primary valve will hold back the hydrostatic pressure whenever particulates are trapped in the primary valve, preventing high pressure jet cutting of the primary seat.

    These valves can be furnished in all materials for corrosion or abrasion resistance and are available as Stellite lined or rubber lined for severe pumping applications.
