Characterises the Viscosity/temperature characteristic of a fluid. The smaller the change in viscosity with respect to temperature, the higher the VI (CETOP RP 100). The VI is mathematically calculate

Depending on the requirements placed on the switching characteristics of a valve (e.g. to prevent switching shocks), the switching speed for the intended actuation element must be slowed down. This ge

2-way which ensures for load sensing systems based on several different loads connected in parallel that the load sensing pressure difference remains constant at the metering orifice regardless of the

When selecting a filter, the key parameters of filter fineness , dirt holding capacity, and the Pressure difference on the filter should be taken into consideration. During the evaluation, it is not s

Is produced on changing from the suction side to the pressure side on hydrostatic displacement machines . Due to the pressure drop or increase that occurs in a very short time. The process is all the

In order for the hydraulic fluid to deliver sufficient lubricating effect in plain bearings and under seals , it must have sufficient wetting ability. This is generally the case with HLPD oils .

The basis is Bernoulli's equation for ideal, incompressible fluids: = static pressure + dynamic pressure + geodetic pressure. This equation yields the related energy element as The last term ρ · g · h

Filter element that withstands a differential pressure that is at least as large as the nominal pressure of the system, without damage occurring to its structure or the filter material.

Printed circuit board (PCB) with electronic controller - at European manufacturers mostly in the eurocard format - that is used to control a proportional valve or servo valve. The control card is most

Bistable switching element in which the switching state last used is retained also after the removal of the input signal (memory action).
