Flow in pipes; flow in gaps. Below the critical Reynolds number (depending on the shape of the cross section), a laminar flow will apply. The individual elements of the fluid only move in the directio

Design for controls predominantly found in mobile hydraulics where more than two functions need to be controlled. Banked valves assemblies are mainly controlled manually and are manufactured as a cast

1. program in a digital computer system that together with the characteristics of the computer system forms the basis for the possible operating modes of the digital computer system and in particular

Device used to add heat to the hydraulic fluid. It is required where the temperature of the fluid should also be constant at the start of the operating period. The preheating normally takes place elec

Hydraulic cylinders , which automatically switch at both ends using an integrated switching device.

The pressure loss Δp through a rectangular gap is calculated from the flow Q, the gap-width bg and the 3rd power of the gap-height hg, the overflow length lg of the gap as well as the density ρ and th

Section of a measuring device where what is received from the sensors in terms of signals is prepared, processed and output (displayed). The type and accuracy of measurement data processing must be ta

Time, which passes from the issue of an order until information contained in a memory is localised or read off. For example, in the case of magnetic plates, it is between 20 and 100 ms and considerabl

Valve with four controlled ports. For directional valves: Inlet, cylinder side A and B, outlet.

The more dependent one becomes on determining parameters of fluid devices and systems through trial runs, the more important it is that these results are comparable. Otherwise, the different products
