Digital measuring procedure
general it not possible to completely return the signal to an analogue output signal, however the output can be in the form of an indication on a scale.
Mounting subplate
ports to the rear or to the side. Stacked plates : Individual plates that are designed such that they can be screwed together to form stacked systems. They are used in various designs for hydraulics.
Pilot-controlled valves
large actuation forces are pilot-controlled by a smaller valve ( pilot valve ). Here the pilot valve can be mechanically actuated (e.g. for piloted check valves), pressure actuated (e.g. for pressure valves
Flow coefficient Kv (Kv value) of a valve
drop of 1 bar (VDI 2173). The Kv value is therefore a parameter for the selection of valve sizes. It can be converted to the flow of air, gases, steam and also other pressure mediums. It is stated as a rule
Pressure-flow (p-Q) control of a pump

water. It also ignores the fact that resistance in both flow directions associated with a 4-way valve can vary greatly (by up to 50%).
Average torque
rotation speeds. It then becomes possible to determine the lowest rotation speed at which the motor can still run effectively.
Contamination in operation
from the seals or Ageing products from the hydraulic fluid (sludge among others). Sometimes there can also be water (that has entered the system or condensation).
