Abstract
A valve system includes a valve body defining an inlet, an outlet, and a flow path connecting the inlet in fluid communication with the outlet through one or more flow paths through the valve body. A poppet is slidingly engaged to the valve body for movement along an axis, between a first position allowing flow though the flow path, and a second position blocking flow the flow path. An electrical circuit makes a path through the valve body. A controller is operatively connected to the electrical circuit, configured to monitor electrical resistance of the electrical circuit and to output a signal indicative of open or closed state of the valve based on whether electrical resistance of the electrical circuit is at a first level or at a second level.
