Abstract: The present invention relates to a pressure profiling device (1), particularly for dispensing units of pressurized liquids, comprising a pump (3) adapted to generate a flow of a pressurized liquid in outlet, said pump (3) being configured to be connected, by means of at least one delivery duct (5, 5?), to at least one dispensing unit (7, 7?) of said liquid, a three-way hydraulic fitting (9, 9?) being applied to said at least one delivery duct (5, 5?), configured to divert a first part of said liquid leaving said pump (3) into a bypass duct (11, 11?), a remaining second part of said liquid continuing on said at least one delivery duct (5, 5?), a proportional valve (13, 13?) being applied to said bypass duct (11, 11?), which can be operated to vary the flow rate of said first part of said liquid diverted in said bypass duct (11, 11?) as a function of the degree of opening of said proportional valve (13, 13?) so as to vary the pressure of the remaining second part of said liquid, According to the invention, a re

Abstract: The present invention relates to a proportional valve (1), particularly for fluid dispensing devices, comprising a main body (3) in which an inlet conduit (5) for an inlet fluid to said proportional valve (1) and an outlet conduit (7) for a fluid leaving said proportional valve (1) are defined, said inlet conduit (5) and said outlet conduit (7) being in fluid communication with each other, said proportional valve (1) comprising at least one shutter element (9) arranged between said inlet conduit (5) and said outlet conduit (7) adapted to intercept said fluid, said shutter element (9) comprising a movable fluid sealing element (90) adapted to intercept said fluid at one of said inlet conduit (5) and said outlet conduit (7) and a lever element (92) associated at a first end with said movable fluid sealing element (90) and at a second end with an actuator device (11), said lever element (92) being hinged about said main body (3) at a fulcrum point (94) arranged between said first end and said second end of said

Abstract: A valve for dosing and mixing two fluids includes two respective inlet ducts, a double chamber for controlling the flows, at least one actuator configured to regulate the flow rates of the two fluids to be mixed, an electronic control unit and a Brix degrees optical sensor, arranged on the mixing duct of the mixture of the two fluids and operatively connected to the electronic control unit. The optical sensor is configured to send a measurement and control signal to the electronic control unit to drive the actuator so as to proportionally control the flow rates of the two fluids and, therefore, regulate the mixing ratio of the two fluids.

Abstract: The invention describes a total isolation diverter valve comprising a valve body whereon a main inlet conduit for inletting a fluid, a first outlet conduit for outletting the fluid and at least one second outlet conduit for outletting the fluid are obtained. The first outlet conduit for outletting the fluid is provided with a first fluid adhesion inner surface and the second fluid outlet conduit is provided with a second fluid adhesion inner surface. Between the main fluid inlet conduit and the two fluid outlet conduits a connection channel is interposed. On the connection channel at least one device for perturbing at least one of the first fluid adhesion inner surface and the second fluid adhesion inner surface is provided. The perturbation device is configured so as to cause a deviation of the fluid flow from the first fluid outlet conduit to the second fluid outlet conduit or vice-versa by exploiting a physical effect called Coand{hacek over (a)} effect.

Abstract: The present invention describes a two-stage valve comprising a first stage constituted by a main valve body provided with at least one fluid inlet duct and with at least one fluid outlet duct, between which is interposed at least one shutter element configured to put selectively in fluid communication such ducts. The valve comprises a second stage constituted by a pilot valve body provided with at least one fluid inlet duct and with at least one fluid outlet duct, between which is interposed at least one shutter element configured to put selectively in communication such ducts. The opening of the shutter element of the pilot valve generates a fluid flow passing through the fluid inlet duct of the pilot valve and the fluid outlet duct of the pilot valve, the pressure of such a fluid flow generating the opening of the shutter element of the main valve.
