Sum of all manipulations required to trigger certain functions in the process (in the system) using defined input signals (DIN 19 237). A distinction is made between analogue , digital and binary sign

Implementation of output elements and/or an output unit in a device (DIN 19 237).

Device that sets the delivery flow of a variable pump to zero on reaching a set pressure such that this pressure is maintained in the system (Figure D 71) . This means that all internal and external p

Type of seal for seal applications in which the seal must remain at a distance from the surface to be sealed during specific parts of the operating sequence. For this purpose in the majority of cases

Hard-wired control, in which program changes are provided for and can be performed in a simple manner. These are controls whose program can be changed, for example by reconnecting lines, changing or r

DC solenoid with an almost horizontal force-stroke characteristic curve in the operating range and which can be controlled in proportion to voltage or current ( Figure P 19 ). The latter is preferred

Measures which keep constant the level of what is passing through a throttle in terms of flow rate , regardless of the pressure difference which applies to it ( flow control valve ). Continuously adju
