Abstract: A valve for hydraulic control of fluid flow rate, comprising: a body provided with an inlet opening, an outlet opening and an actuating opening; a rotating hollow shutter rotatively housed inside said body, said rotating shutter being configured to be crossed by a fluid and to change the passage cross-section inside the valve, in which the rotating shutter comprises at least one first opening rotatively cooperating with at least one mated second eccentric opening, said rotating shutter being configured to be manually actuatable inside the body so that a rotation of said first opening with respect to said second opening is matched by a variation of the fluid passage cross-section in a direction substantially coinciding with the rotation axis.

Abstract: A filtering group comprising a connection structure having a first input coupling in communication with an input conduit and an output coupling in communication with an output conduit. Further comprising a filter body connected to the connection structure and in fluid communication with the output coupling, and a ball valve housed in the connection structure and configured to assume a first position defined as when the first input coupling is placed in fluid communication with the filter body and a second position defined as when fluid communication between the first input coupling and the filter body is interdicted. The connection structure also includes a second input coupling in communication with the supply line as an alternative to the first input coupling and oriented, with respect to the output coupling, differently from the first input coupling.

Abstract: A deaerator with integrated shut-off valve comprising a detachable hollow body having a lower part of a cup-shaped body having an inlet connectable to a hydraulic manifold, and an upper part of the cup-shaped body having a vent opening. The upper part is configured to be stabilized the lower part to define a deaeration chamber. The deaerator may include a float assembly having a float element and a drive mechanism. The deaerator may further include a shutter slidingly arranged through said inlet opening of said lower portion, and a head arranged on the inner end of the body. The shutter may include a collar to block the passage of liquid through the opening when the upper part is detached from the lower part of the same body.

Abstract: A cartridge flow rate adjusting assembly for a hydraulic valve, may include a cartridge body, a stem that is slidingly disposed in the cartridge body, and a shutter to be slidingly placed against a passage opening. The cartridge flow rate adjusting assembly may further include a sleeve rotatively disposed inside the valve that may include at least one first opening to enable adjustment of a maximum flow rate of the valve within a first range of values, and according to a first scale at least one second opening made in the wall to enable adjustment of the maximum flow rate of the valve within a second range of values according to a second scale. A hydraulic control valve is also provided that comprises a cartridge flow rate adjusting assembly.

Abstract: A cartridge flow rate adjusting assembly of a hydraulic valve may include a rod having a first end and a second end, a shutter integrally formed with the first end of the rod and to slidingly positioned against a passage opening of the valve for adjusting flow. The assembly may also include an elastic element to hold the rod with the shutter in a monostable position with the opening of the valve. A plunger element may be integrally formed with the rod and interposed between the shutter and second end. The assembly may further include a conduit formed in the rod. The opening of the valve may be in fluid communication with a portion of the chamber disposed between the plunger and second end so that a pressure in the portion of the chamber is equal to a pressure in the passage opening.

Abstract: A multiway valve may include a generally cylindrical shaped hollow valve body having at least one handling opening and a plurality of through openings made on the outer wall of the valve body and defining a first group of connecting openings and a second group of connecting openings. A handling element may be pivotally disposed in the valve body and include at least two first through radial openings made on the outer wall of the cartridge. A tubular shaped fluidynamic insert may be housed inside the cartridge, and may have a second radial opening to let a fluid flow. The fluidynamic insert may also include a cell formed inside the cavity of the insert to define a homogeneous fluid flow rate.

Abstract: A multiway valve, comprising integrally connected first and second valves. Each valve comprises a valve body comprising a user port, a source port and an intermediate chamber placed therebetween, and a shutter inside the intermediate chamber, having a passage orifice for fluid to pass therethrough. The multiway valve comprises movement means allowing the shutters to move between a closed position where each passage orifice faces the inner walls of the respective intermediate chamber to an open position allowing the passage of the fluid between the user and source ports through the passage orifice. The first valve comprises a bypass duct formed in the shutter opening in fluid communication with the passage orifice. The bypass duct allows fluid communication between the intermediate chamber, the passage orifice, the duct, and the user and source ports of the first valve when the shutter is in its closed position.
