An illustrative valve cartridge for a pump system is disclosed. In one example the valve cartridge includes a cartridge body, a mounting flange operatively coupled to the cartridge body, wherein the mounting flange is adapted to be coupled to a housing of a pump, a valve member that is adapted to sealingly engage a valve seat within the pump housing and an actuator positioned within the cartridge body, wherein the actuator is operatively coupled to the valve member via a connector and wherein the actuator is adapted for selectively moving the valve member relative to the valve seat when the valve cartridge is operatively coupled to the pump housing.
