an apparatus , a method and a system control fluid flow through a passageway . a downhole tool pumping apparatus may have a body and an active valve block . the body has a cavity housing a reciprocating piston defining first and second chambers within the cavity . the active valve block has active valves configured to be actively actuated between an open position and the closed position . two or more hydraulic lines may be connected to each active valve for controlling actuating between the open position and the closed position . a piston having a conduit is slidably disposed through the passageway and selectively closes the conduit of the piston by moving at least one of the piston and a plug .
