Abstract: A bypass valve, comprising: a main conduit (10), comprising a first section (11) and a second section (12); a mobile control shutter (21); a bypass conduit (30) which places the main conduit (10) in communication with a discharge opening; a control element (31), mobile between a closed position, at which it closes the bypass conduit (30), and an open position, at which it opens the bypass conduit; a throttle element (40), interposed between the first section (11) and the second section (12), structured to produce a load loss which depends on the fluid flow rate in transit along the main conduit (10). The control element (31) is tubular-shaped and defines internally a section of the bypass conduit (30). The control element (31) is slidable along a housing (32) provided with a sealing seat (33). A passageway (34) is predisposed between the control element (31) and the housing (32) which places the first section (11) in communication with the second section (12).

Abstract: A pressure regulating bypass valve (1) comprises a hollow element (10) internally defining a chamber (C); an interception member (20) housed inside the chamber (C) and that is slidably movable between a discharge position and a delivery position; and an elastic means (30) configured to exert an elastic force on the interception member (20) so as to push the interception member (20) towards the discharge position and determine a positioning and/or movement of the interception member (20) between the discharge position and the delivery position; the interception member (20) is further positionable in an intermediate position between the discharge and delivery positions.
