Preadjustments < 5 are not recommended because the stroke resolution is too small.

pressure drop Δp of 1 bar across the valve.
· The preadjusting ring permits 2 full revolutions.
The values given in the table (reference numbers

) define the first revolution. After another
revolution (reference number 0

still increases to 2.5 mm (fully open), but the k

· The valves are supplied with the preadjusting

). To
make a preadjustment, the ring must first be fully
closed – only then can the required reference
