Unlockable check valve with twin design. The shut-off unit is arranged to compensate for leaks from directional valves with a piston structure between the consumer (e.g. cylinder ) and the directional

Proportion of the time Tb for which a system or device (e.g. pump) is in operation during a specific period of time T s (e.g. a month or year). The duty ratio, besides what is required by way of relia

"Closed circuit". As the English term "Control" applies to both open loop control and , closed loop normally refers feedback control. Opposite: open loop

Retains the instantaneous value for an input signal recorded by a sampler as the output signal until the next sampling (DIN 19 226).

Process in a system/device during the transition phase to achieving a steady-state if the system/device has been excited by a step function . The settling process therefore shows how a transfer elemen

Change in the input signal that is necessary to generate a measurable change in the output signal, if the input signal is changed from a static point in the same direction in which the static point wa

Valve with a proportional connection between the input signal and the flow rate in a working line (consumer port) and in one effective direction. This includes construction designs of proportional flo

The lifetime is the period during which a device or system is expected to remain functional as expressed by the number of achievable or achieved actuations under certain specified conditions.
