Component that actuates a device (e.g. valve ). This can be a lever or cam ( mechanical actuation ), a solenoid or electric motor ( electric actuation ) or a piston or cylinder ( pressure actuation ).

In a normal controller the main tasks for signal handling and signal processing arise in the setpoint branch (e.g. time profiles, ramps etc.). Such tasks can be resolved all the better digitally, the

Roof-shaped, low height seal shape of which several, often with different materials, are assembled to form roof-shaped seal sets (Figure D 1) . In principle a differentiation is made between two forms

Parameters for the behaviour of elastomer materials in different hydraulic fluids that can range from shrinkage, through slight swelling, to complete dissolution of the elastomer. If the DVI of the in

Temperature, at which a liquid can no longer flow under the effect of its own mass when cooled down under defined conditions. In the course of adapting to international standards, the setting point wa

Process with the aim of triggering a certain movement (function) by actuating individual valves or controls .

Hydraulic cylinder mass-produced in accordance with the relevant standards. These are the nominal pressures as per ISO 3322, diameter of cylinder bores and piston rods as per DIN ISO 3320, surface rat

ν was previously given in degrees Engler (°E), and then in stokes or centistokes (cSt), but is now given in m 2 /s or mm 2 /s. cSt can be converted as follows: 1 cSt = 1 mm 2 /s The kinematic viscosit
