Abstract:
Valve module for influencing a fluid supply of a fluid-operated load, comprising a valve housing with a valve chamber being connected to an inlet port and an outlet port and a pilot chamber being connected to an operating port, comprising a valve member which is movably adjustable between a blocking position and a release position and further comprising an actuator which is motion-coupled to the valve member, wherein a position of the actuator and the valve member can be set as a function of a pressure applied to the pilot chamber, and further comprising a sensor device for detecting a position of the valve member and/or the actuator along a movement axis, and the sensor device comprises an electric coil arrangement which forms a ring around at least one fluid port from the group comprising the operating port, the inlet port and the outlet port.
