individual function blocks are stacked on one another like a tower ( Figure T 20 ). In this way, valves can be fitted on three or four free surfaces.

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 be used, given appropriate operation [...] inserted in a bore in accordance with DIN 24 342 and that are sealed upwards by a control plate. They can also be in the form of spool valves as normally closed or normally open valves ( Figure Z 17 ). The [...] switching functions or a proportional valve for continuous functions. The pressure and flow valves can also be operated by conventional means or using proportional valves. The circuit symbols are defined

with a variable pump ) and can only operate one load at a time ( Figure K 30 ). If there is more than one load in a system, these must be connected in such a way that they can only be operated one after

DIN 19 226). The pilot control behaviour can be significantly affected by suitable controller concepts. The damping in a closed circuit position control system can be removed to a large extent by feeding

which the geometric displacement per cycle can be changed. For design-based reasons, this is only possible for vane and piston constructions. Variable pumps can be adjusted from the maximum to zero or through

divider valves that they work without inherent throttle losses, that the subflows can also be different in terms of amounts and can result in improved accuracy (approx. 1-1.5% leakage losses). Toothed wheel flow

gradient on the pressure-signal function , e.g. 2,000 bar/mA. It is crucial for the accuracy that can be achieved with a controller.

Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in the form of a seated valve or ball valve . The valve is actuated manually, magnetically or using a

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 ).
