Abstract
A regulating valve has a valve body, with an inlet and an outlet for fluid, which are connected by a connecting opening, and a flow control device for the connecting opening, inserted in a seat formed in the valve body. The flow control device has a piston for controlling flow within the connecting opening which is functionally connected to an electric motor adapted to make it slide within a cylinder along a sliding axis, and a monolithic tubular jacket that surrounds, determining its coaxiality, the rotor of the electric motor and the flow control piston, further providing the cylinder.
