Pipe screw connections
Elements used to create removable connections for pipelines and devices. They are manufactured for three pressure stages (LL - very light, L - light, S - heavy). A distinction is made between three di
Test signals
All signals of sensors that are used to check device functions. Test signals are also all signals routed over interfaces to monitor the operating status of the device, e.g. actual value, solenoid curr
Directional valve
Fluid valve with binary behaviour, i.e. it moves from one switching position to another (e.g. Open – Closed) without adopting an intermediate position.
Grooved ring seal
Oldest form of elastic seals . They can be used as two lip seals for sealing at the inner and outer ring (Figure N 9 a) or as a single-lip ring with an adhesive section for single-sided sealing. The s
Piston machines
Hydrostatic displacement machines , displacement chamber machines , pump with banked pistons/in-line piston pump
Filtration efficiency in general
Ability of a filter to retain specific test contamination in a hydraulic fluid with a specified contamination concentration under defined test conditions (CETOP RP 100). As the test method for filtrat
Signal switch
Electrical arrangement to split an input signal into two .
Safety regulations
In terms of fluid technology there is no closed regulatory system in terms of safety technological requirements. Rather, these are distributed over a series of rules, regulations and standards of the
Motor control (open-loop)
Stroking of hydrostatic machines
Continuous value
the signal parameter can assume all values of an interval (e.g. all voltage values between -10 and +10 V if the voltage is the signal parameter) (DIN 19 225).
