Abstract: Ball valve with a housing which forms an inlet, an outlet and an obturator seat, an obturator which forms an inner cavity with an inlet aperture, an outlet aperture opposite the inlet aperture, an auxiliary aperture between the inlet aperture and the outlet aperture, as well as a closed side opposite the auxiliary aperture. The inlet aperture and the outlet aperture connect the inlet with the inner cavity and with the obturator seat and an outer channel is formed in an outer surface of the closed side which, when the obturator is rotated from a closed position towards an open position, opens a first outer flow passage between the obturator seat and the outlet before the outlet aperture opens a second inner flow passage between the inner cavity and the outlet.

Abstract: A ball valve including a valve body with connection portions, one or more threaded ring-nuts screwable to the connection portions to connect them, a control handle and a ring-nut spanner tool suitable for engaging the ring-nut to screw and unscrew the ring-nuts from the connection portions. The ring-nut spanner tool is housed in a rest position in the control handle and can be moved from the rest position to a working position outside the control handle. In the working position, the ring-nut spanner tool can engage the ring-nut.

Abstract: A device for conveying and/or distributing fluids comprises a housing with connection portions, one or more threaded ring nuts which can be screwed to the connection portions for joining them, and a tightening seat formed in the housing. The device further comprises a first adapter with a portion for coupling with the tightening seat, a driving portion for engagement with an engagement portion of the ring nut and a first key seat shaped to receive a portion for coupling a tightening tool.

Abstract: A device for conveying and/or distributing fluids comprises a housing with connection portions, one or more threaded ring nuts that can be screwed to the connection portions in order to join them, a control handle and a tightening seat formed in the housing and adapted to support the control handle in a tightening position, rotatable around a tightening axis. The control handle comprises a drive portion which, in the tightening position, engages with a coupling portion of the ring nut, in a manner such that a rotation of the control handle around the tightening axis leads to a screwing or an unscrewing of the ring nut.

Abstract: A fluid conveying and/or delivering device (1) comprises a housing (2) with connecting portions (7), as well as a labeling module (5) with a label seat (6) to accommodate an identification label (8) and a protection lid (9) being removably connected to the device (1) such as to close the label seat (6) outwardly of the device (1), wherein the protection lid (9) comprises a transparent window (10) allowing to view the identification label (8) within the label seat (6) from the outside of protection lid (9).

Abstract: An anti-unscrewing device for coupling the tubular ends of two components in fluid conveying or delivery systems by means of a threaded ring nut that can be screwed to one of said tubular ends to connect said ends, wherein said anti-unscrewing device comprises a connecting portion to connect the device to one of the components and at least one counter element provided with an engaging portion suitable to engage a corresponding engaging surface formed at said ring nut, such that the engaging portion can be displaced by means of a movement of the ring nut. There are further provided guide means dictating a movement path for the counter element, such that an unscrewing movement of the ring nut will cause the engaging portion to move to a locking position relative to the ring nut thereby preventing the ring nut from unscrewing.
