Special form of expert system that is designed to cover all realistically possible errors and that is capable of preparing a cause-effect analysis to suit the requirements and criteria of the user. Di

Ball seated valve : Directional or check valve with a freely moving ball as the blocking element. Excellent in terms of keeping designs simple, but is only suitable for small valve sizes. 2/2-way ball

General : Pressure set on a device (DIN 24 312). On pressure-limiting and safety valves (DIN 3320): set pressure p e is the pressure at which in test stand conditions (atmospheric back pressure), dire

Operating pressure

In general : Flow rate to supply the hydraulic actuation of devices. With continuously adjustable valves : A distinction is made between the resting value of the control flow rate as its value in a st

Volume (bulk) filters

Pressure that is preselected in the case of p/Q regulated hydraulic pumps as the pressure in the zero stroke phase on the proportional valve to minimise the power losses in dry runs. It is generally b

Controls can be designed in very different ways and with highly different controller structures to achieve a certain pilot control behaviour . It then becomes a case of control concepts. The control c

Devices — located along the signal flow — which make up a measuring device and whose measuring characteristics (errors, chain of influences) are specific to the measuring device in question ( Figure M

A hydraulic power pack is a stand-alone assembly consisting of a drive motor, hydraulic pump and hydraulic fluid tank. The drive motor is connected to the hydraulic pump via a shaft and drives this. T
