Piston position in hydraulic valves

Servo and proportional valves regulate the volume flow in hydraulic systems. Displacement sensors are necessary for precise control. Inductive displacement sensors mounted on a pressure tube outside the pressure section are used for this. From this position, they measure on the piston through the pressure tube for an exact regulation.
