Screw-in cartridge valve
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
Screw-in throttle
Throttle valve that is designed as a screw-in cartridge.
Spring accumulator
Hydraulic accumulator on which a spring is used for the pressure load. This solution is only suitable for very small accumulators, as otherwise the spring and therefore the overall dimensions will be
Spring reset
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
Elastic pipe (bourdon type) pressure measurement devices
Most important group of pressure gauges on which the measuring organ deforms elastically and proportionally to the pressure. This deformation is therefore a direct measure of the magnitude of the pres
Fail safe
Safety circuit for the elimination of a faulty device or part of a control system with redundant circuits. The signal is generally triggered by measures for fault detection .
European circuit board
Standardised dimensions of a printed circuit board of 100 x 160 mm for mounting all necessary electronic components for a control or a part of a control. The European circuit board is used to standard
Equivalent time constant
This includes the Delay T u as the time defined by the time from the arrival of the control signal to the intersection of the inflection line with the abscissa and the Settling time T g as the time de
