The positioning unit is for a multi-way valve and comprises a coupling component for its connection to a multi-way valve. The coupling component is turnable and at each of its two ends has central apertures, of which the one works in conjunction with coupling surfaces on an outer end of a first type of valve shaft and of which the other works in conjunction with coupling surfaces on an outer end of a second type of valve shaft. Cogged disks encompass the apertures and when they are turned towards the valve positioning unit they work in conjunction with cogs on a facing end of a manoeuvre shaft incorporated in the valve positioning unit. |
