system from surpassing a predefined overpressure and is intended to automatically close again after a drop in pressure. The requirements placed on a safety valve are described in the Pressure Equipment Directive

g. a limit load high response proportional valve measures via a measuring orifice a rotation speed drop (engine loading), which results in a reduction in the variable pressure at the pump adjustment and

defined by the number of particles before and after passing through the filter with a specific pressure drop (Figure B 13) : Therefore at β x = 1 no particles are removed; 50 % of the particles are removed at

it is not possible to achieve a constant flow rate. It is only in the case of a constant pressure drop (at constant oil viscosity) that a constant flow rate is created at a throttle. As a result, load

downstream must first be used instead of an upstream pressure compensator. The value of the pressure drop determined by this pressure compensator can be compared directly with the value of a second valve

advantages of proportional technology are as follows: direction and flow control in a valve, low pressure drop at control edges, mastery of acceleration and deceleration processes via electronic specifications

dynamic pressure is constant: This means that in places of high flow velocity the static pressure drops such that air separation or even cavitation can occur. Orifice law : This law defines the outlet velocity
