Pneumatically or electrically actuated directional valve whereby reversal occurs via a pressure pulse at one side of the valve control spool or a short electrical signal at a solenoid. The valve remai

Synonym: Frequently used expression for the velocity (dynamic) pressure

Group of elastic materials, which become soft (thermoelastic) when energy is added (temperature increase), where moulded parts lose their form (voltage). When cooling, plastification of the materials

Feature that on some adjusting features on pumps, e.g. power controllers, reduces or limits the pump delivery flow on reaching an upper adjustable pressure to prevent the pressure-limiting valve trigg

Flow rate which continues to flow for proportional valves, high response proportional valves and servo valves when the consumer ports are closed and at a system pressure p o. It results from the leaka

Ratio of the output power to the input power of a system or device ( total efficiency in the case of hydraulic devices).

Devices, which control a power flow. In fluid technology these are the valves, which influence the flow rate in terms of direction ( directional valves ), size ( flow valves ) and pressure ( pressure

The standard for the multipass test is set out under ISO 4572. Test method for determining the filtration efficiency in general ( retention rate, filtering grade ). This involves passing a specific mi

Reaction force generated if a fluid flow changes direction and/or velocity. The force F acts on the fluid from the outside as a supporting force. The force exercised by the flow on the environment is
