Lasting pressure reduction as a consequence of energy conversion (e.g. at a flow resistance ) (DIN 24 312). The pressure loss along with the leakage loss is the most important source of loss in hydrau

Provides information on the magnitude of the Δp of directional and check valves depending on the flow rate Q (Figure D 78) . The pressure drop-flow rate chart is an important parameter for assessing a

On compressors: Ratio of the absolute final pressure to the absolute inlet pressure on a compressor. The pressure ratio on a multi-stage compressor is given by the ratio of the absolute inlet pressure

Valve that maintains the ratio of outlet pressure to inlet pressure constant.

If an elastic material (elastomer or specific thermoplastics) is excessively deformed under pressure, lasting deformation may be caused such that after the end of the pressure action only part of the

English unit of pressure. Conversion: 1 bar = 14.5 psi and 1 psi = 0.07 bar (i.e. 1 000 psi = 70 bar).

System to review the correct functioning and the operational safety of the static and dynamic behaviour, as well as the correct functioning of technical devices and assemblies.
