Abstract:
A control valve including: a valve body, a flow shutter operatively interposed between an inlet and an outlet, a driving spindle having at least a first actuating end and a second end connected to the flow shutter. The valve also includes a differential pressure automatic regulation device, comprising: a cup-shaped body arranged around the driving spindle and axially mobile with respect to said driving spindle; a spring operatively interposed between the valve body and the cup-shaped body to push the latter away from the flow shutter; a rolling membrane having a radially inner edge fixed to the cup-shaped body and a radially outer edge fixed to the valve body to delimit a first chamber in fluid communication with the inlet and a second chamber in fluid communication with the outlet.
