1. Set to the desired step according to calculation (digital display on the hand wheel).
2. Remove the hand wheel securing screw
3. Screw the presetting spindle, which is now accessible, in up to the stop.
4. Replace the hand wheel securing screw.
Max. operating temperature 120 °C
Max. operating pressure 20 bar
•The flow rate through orifice is constant for all preset values, i.e. quick and easy balancing
•Infinitely adjustable presetting, the flow rate which goes through the orifice is precisely controlled
•Through the use of an integrated orifice, the pressure drop is very precisely measurable
•Kv-value of integrated orifice is shown in the descriptive table – Accuracy ± 5%
