Abstract: A control assembly of a solenoid valve for a delivery device; the control assembly comprising a first input configured to be coupled to a control device of the delivery device and to be supplied by a power supply voltage from the control device; a first output configured to be coupled to a second input of a solenoid valve; a control unit being coupled to the first input; and a drive unit coupled to the first output and to the control unit; the control unit being configured to detect a first voltage at the first input; the control unit being configured to control the drive unit so that, when the control unit detects a first voltage equal to a power supply voltage, the first output of the control assembly delivers: a rated voltage for a first period of time, and a hold voltage different from the rated voltage for a second period of time following the first period of time, and wherein the hold voltage is lower than the rated voltage.

Abstract: A hydraulic assembly for controlling a liquid is provided with a plurality of hydraulic modules connected to one another; wherein each hydraulic module comprises a base element in which a liquid runs in use; a base element comprising a base body, a first connector and at least one second connector; the first connector and the second connector can be mutually coupled; and an interactive element, coupled to the base element and configured to interact with the liquid running in the base element.

Abstract: A valve, in particular for water discharge of toilets, has a valve body having at least one feed port and a delivery port; a shutter assembly movable with respect to the valve body between an open position and a closed position; an auxiliary channel, which has the function of controlling the shutter assembly, extends from the feed port to the delivery port through the shutter assembly; a first auxiliary shutter controlled electrically for selectively closing the auxiliary channel; and a second auxiliary shutter for selectively closing the auxiliary channel as a function of the pressure generated by the opening of the first auxiliary shutter.

Abstract: An assembly for the connection of tubular members is provided with a connection sleeve which is suited to connect one to the other a first tubular member and a second tubular member, and an intermediate coupling ring mounted to slide along at least an intermediate coupling portion of the first tubular member; the coupling portion having a diameter ranging from a minimum to a maximum so that the sliding of the coupling ring (4) along the coupling portion causes the deformation of the coupling ring in a locking configuration of the connection sleeve to the first tubular member.

Abstract: An on-off flow valve extends along an axis and has a valve body through which a supply duct and a delivery duct pass; a main shutter assembly; and a cover fitted to the valve body by means of a snap-on coupling system.
