Copying valve
Hydro-mechanical continuously adjustable valve which mechanically samples the contours of a template (containing information regarding the shape of a workpiece) and converts these into a distance, pro
Hydropneumatic accumulator
Hydraulic accumulator that uses a gas as the medium for applying a load to the hydraulic fluid (air for accumulators for water hydraulics , nitrogen for oil accumulators). As a consequence of the gas
Nominal power
Power of a device (pump, motor, valve ) within defined parameters.
Valve control spool
Control element in directional , pressure and flow valves with a piston shape, which is generally countersunk, i.e. sealed with gap seals .
Reactionless transfer
A reactionless transfer takes place in a or control if the signal transfer is targeted, i..e changes to the output do not affect the input variable.
Naphta based oil
The 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 u
Processing of actual values (or signals)
General : If the actual value cannot be processed directly in its present form, it will first need to be pre-processed in a suitable manner, i.e. converted for processing. Processing of actual values
Fine control of flow
The controllability of very small flow rates in continuously adjustable valves requires special measures on the control edges . In servo valves straight control edges with high precision are used (zer
Linear motor
Device which generates a linear movement directly. This is the hydraulic cylinder as hydraulic linear motor and the solenoid or electric linear motor in electric drives.
