Valve as an additional backup for the closing movement of a hydraulic cylinder , e.g. for pressing or injection moulding machines. The valve is operated by the movable protective grid of the machine i

If hydraulic valves receive their own electronic control onboard and thus their own intelligence, they can work completely independently and also offer numerous additional functions. The electronic co

Leakage occurring inside a device. It is not visible from the outside, but can involve a loss of power. With pumps, for example, this may be a flow of leaking oil from the high-pressure side towards t

The most important parameters for the effectiveness of filters are: Alpha value of filters , Beta value (β value) , Filter cumulative efficiency , (degree of retention), Dirt holding capacity of a fil

Flow rate/pressure characteristic

Assembly option for hydraulic control valves whereby a valve is assembled in each case on a mounting subplate containing up to five ducts and it is possible to bolt them together as required. It ends

Entirety of the static and dynamic properties of a final controlling device in physical/technical terms and in terms of transmission (DIN 19 237).

Describes the flow rate-pressure characteristic of a concentric flow resistance ( orifice , Bernoulli's principle). Does not apply for laminar flow resistance (e.g. capillary tube ).

Flow rate escaping from pressure compartments in spite of seals , particularly in systems with purely metallic seals, without contributing any useful work. Apart from the geometric variables associate

according to VDI 3260 Graphic description of the movement sequence of hydraulic systems from which the individual steps and their sequence for a switching cycle are defined, as can be seen in (Figure
