Change of the input signal , at which the valve power output is reversed at zero. It is expressed as a percentage of the input signal.

. Welded nipple pipe screw fittings with connectors and union nuts are standardised in DIN 2353. The welded nipples with O-rings are in accordance with DIN 3865.

A floating measuring body is raised by the flow rate in a conical measuring pipe until a balance is reached between the weight of the floating body and the flow resistance ( Figure S 39 ). This means
