Abstract
A hydraulic cartridge valve includes a movable member and a position monitoring mechanism configured to detect the position of the movable member. The position monitoring mechanism is adapted to generate a position signal indicative of the position of the movable member. The position monitoring mechanism can be in the form of a linear variable differential transformer (LVDT).
