The present disclosure relates to valve systems that include valve shift detection systems that can be employed to determine when a valve has shifted. According to certain embodiments, the valve shift detection systems may include a switch integrated into a valve block that may be closed upon shifting of the spool valve. In certain embodiments, the switch may include a component that completes a circuit upon contacting the valve. The valve shift detection systems also may include a controller designed to detect a voltage or current change produced by completing the circuit.
