Valve Shift Detection Systems and Methods

摘要

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.

主权项

1. A valve system comprising:
a valve disposed in a housing and comprising a spool moveable from an un-actuated position to an actuated position in response to actuation of the valve; and a valve shift detection system disposed in the housing and comprising a circuit electrically isolated from the valve in the un-actuated position and electrically coupled to the valve in the actuated position.
