Manual and automatic driving system for valves, fixing joint for such system and supplying kit thereof

Abstract

The driving system according to the invention comprises a motor-driven actuator (1), a valve (2) and a joint (3′) connecting them. The joint (3′) includes a connecting shaft (50′) having a hole (506) arranged to receive the end of a lever (6′). By inserting the lever (6′) into the passage left open by the opening (320) and the hole (506), the connecting shaft (50′) is disconnected from the actuator (1) and the stopper (280) of the valve (2) can be manually rotated without damaging the actuator itself. When not in use, the lever (6′) can be removed from the hole (6′) so that the lever does not create dangers. The invention further concerns the joint (3) connecting the actuator (1) and the valve (2), and the kit for supplying the lever (6′) along with the joint (3) and possibly the valve (2) or the actuator (1).
