Compares the value of an input variable with a limit. If this limit is exceeded or dropped below, the limit signal changes (DIN 19 237).

Possibility of movement of a rigid body in a reference system. Six degrees of freedom are given, e.g., by three translatory and three rotary movement features.

Area of drive technology that uses the conversion, control, feedback control and transmission of energy by means of a fluid or gaseous hydraulic fluid to solve drive tasks.

The moving parts of the device are placed in the initial position by spring force after the actuating force has been removed (e.g. in spring-centred directional valves or spring pre-load on check valv

Type of valve in which the housing is not required and is replaced by corresponding recesses in the block into which the valve internals are screwed (e.g. on directional valves the valve sleeve with t

Valve assembly method in which individual function blocks of a machine control are connected together to form vertical stacking assemblies above each other or to form series connections (beside each o

Device for turning movements (swivelling) at a limited angle (approx. 60° up to a maximum of 360°). A distinction is made between ( Figure S 41 ): The most simple construction type, which requires the
