Abstract: A ball valve (10) is described comprising a valve body (12) in which an axial channel (14) for the unidirectional flow of a fluid is obtained. The axial channel (14) extends between an inlet port (11) and an outlet port (13) for the fluid, wherein the ports are axially aligned with the axis of the axial channel (14). The valve is provided with a motorized actuator (20) for adjusting the position of the fluid adjusting ball (15) and comprises a head block (17) for installing the motorized actuator (20) on the valve body (12). The head block (17) includes at least one stem (21) for rotating the ball (15). The valve body (12) has a first window (26) whose axis is coincident with the axis of rotation of the ball (15) and at least one second window (27) whose axis is coincident with the axis of rotation of the ball (15).

Abstract: A fluid control valve with a butterfly-type flow control element, with high operating reliability, comprising a valve body which is crossed by a passage with an inlet and an outlet which can be connected to two branches of a duct for a fluid to be controlled by means of the valve. The valve body accommodates, in an intermediate region of the passage, a butterfly-type flow control element which can be actuated in order to open or close the passage. The valve body supports, in the intermediate region of the passage, an annular gasket which can be engaged by the flow control element in the closure position. The valve body is provided in at least two parts which are mutually coupled at the region that is occupied by the annular gasket and lock the annular gasket between the parts in a mutual coupling position.

Abstract: A fluid flow control valve with integrated pneumatic actuation, comprising a valve body which forms, inside it, a passage chamber for a fluid which is connected to an intake port and a delivery port. A sealing region is formed inside the passage chamber, between the intake port and the delivery port, and can be engaged by the head of a pneumatically actuated flow control element which can move on command along an actuation path in order to pass from an open position, in which the head is disengaged and spaced from the sealing region, to a closed position, in which the head engages the sealing region.
