De-emulsifying mineral oils
and occasionally with the assistance of special admixtures, are able to rapidly separate out any water. This action is preferred above all in hydraulics with larger filling volumes and with the more frequent
Shut-off unit
Unlockable check valve with twin design. The shut-off unit is arranged to compensate for leaks from directional valves with a piston structure between the consumer (e.g. cylinder ) and the directional
Multi-loop feedback control circuits
With multi-loop feedback control circuits, several physical variables are recorded during the process and processed in accordance with various algorithms . These include cascaded (multi loop) control systems
Contact pressure gauge
Standard pressure gauge with a spring-based elastic measuring element which features a spring contact in addition to the pointer with its electrical limit value indicators to ensure there is an upper and
Two edge control
displacement chamber with a type A hydraulic half bridge (adjustable input and output resistance); use of both control edges of a continuously adjustable 3/2-way directional valve with negative pressure. [...] Together with a differential cylinder with an annular area pressurised at operating pressure (replacement circuit for hydraulic bridge D), the two edge control enables movement control. One example is [...] than the valve control with four edges , as only two control edges have to be adapted to one another. However, it does not achieve the force gain and accuracy of a valve control with four edges . 2. Hydraulic
Axial piston motor
As with axial piston pumps, axial piston motors are also available in the bent axis and swash plate designs; both variants with fixed and adjustable displacement. The following sectional drawing shows
Self-tuning controllers
Automatic controller settings with self-teaching systems or identification processes or similar methods. The self-tuning of controllers is intended to accelerate difficult and arduous initial settings [...] settings of fluid technological regulations and thereby reduce a significant disadvantage compared with electrical .
Analogue controller
Controller on which the input and are analogue signals . Also controller with analogue, and with continuous and time-continuous , i.e. progressive input and output signals today often have a digital computer
Naphta based oil
for seals to swell significantly, which is why elastomers with a high ACN content are required in this context. They are also associated with poor VT behaviour. Alternative: paraffin base oil. [...] base oil is of the naptha variety. Naphta based oil has a high aromatic content and is associated with low viscosity (VG 15 to 10). Because of their low pour point , these oils are predominantly used outdoors
Plug amplifier
Control electronics that are integrated into a larger magnetic plug with a configuration in accordance with DIN 43650. Control electronics integrated in a magnetic plug for proportional valves . The electronic [...] digital input signal into a PWM output signal. The configuration is normally defined in accordance with DIN EN 175301-803. The plug amplifier is normally configured using buttons, potentiometers, bus connection
