Means working "with numbers". This signifies the representation of variables using an agreed set of characters that are assigned to the variable to be represented by a code . If the variable to be represented

applies to it ( flow control valve ). Continuously adjustable valves are combined for this purpose with a , which can be arranged at the inlet or the outlet ( Figure L 8 ).

actuations or to protect against overloading. The safety elements required for this, such as valves with a redundant design, electrical monitoring of switching procedures, protection against unauthorised

direction of the flow. As a result of viscosity, the local velocity across the cross section is associated with a kind of parabolic distribution

the computing element (device, program ) within the which continuously compares the control variable with the reference variable and forms the correcting variable from the difference ( control deviation ) [...] In order to achieve a stable feedback control, the properties of the controller must be coordinated with the controlled subsystem, . There are various controller types and controller concepts available for

made between single-acting ( plunger pistons ) and double-acting pistons ( differential pistons ). With the latter, the piston is set down on the diameter of the piston rod (area A St). This results in [...] annular area A R, which is also the return area for differential cylinders ( ratio of piston areas α). With single-acting pistons by contrast, the piston is also the piston rod.

accordance with the respective requirements, since errors occurring between the comparison position and the measuring position in the forwards branch of a are suppressed in accordance with the loop gain

cheaper energy consumption in many application cases, compared with all other types of duty. Intermittent operation is comparable with start-stop systems in motor vehicles.

some circumstances even with the multiple operation of an individual plug-in valve. The layout is typically that of seated valves that are inserted in a bore in accordance with DIN 24 342 and that are [...] function of a 4-direction valve is replaced by four single valves that can now be operated, e.g. also with overlaps ( Figure Z 16 ). This procedure is cost effective because the same basic 2/2 unit can also

fluid to reduce mechanical wear on moving parts of a hydraulic system which it comes into contact with. To improve the wear protection capacity, wear protection agents are added (normally phosphate compounds)
