Valve assembly system in which either all valves for a machine control or only individual, recurring function groups (function blocks) are arranged on a block. In both cases the block has the task of

Plate for covering valve stations on a group plate (stacked plate). They are used if an additional device is to be fitted later.

Local flow resistance with step cross-section constriction in which the ratio between the length l and the diameter d is relatively small (Figure B 18) : The smallest flow cross-section is outside the

Discrete signals with a finite number of value ranges for the signal parameter where each value range is assigned as a whole to a specific item of information. Digital signals can also have multiple p

Connection together of digital modules with simple or complex functions ( integrated circuits ) to form complete controls.

Change in the input variable that changes the output variable by the smallest digital step (1 D = 1 Digit).

As almost all measured variables in fluid technology change in an analogue manner, they must first be divided up into equal size sections (steps) for digital measured value acquisition. This action ca

Procedure in which the measured variable is assigned to an output variable that is a numeric representation of the measured variable quantised using pre-defined minimum step (according to DIN 1319). M

Recording and acquiring or saving measured results using digital devices. As almost all measured variables change in an analogue manner, it is necessary to divide them up into equal size sections also

Converts digital input signals into analogue output signals, i.e. into a proportional DC voltage. In conjunction with digitised signal processing provided by microelectronics, D/A converters are requi
