  • Patent number: 9964964
    Abstract: An automatic balancing valve is described, wherein a flow controller device is provided and comprises at least translationally movable plug and a respective valve seat that cooperates with the plug in order to automatically adjust the fluid flow rate through the valve. A ring nut, combined with the flow controller device, is rotationally hand-operated to move a choking member placed inside the valve. The movement transmission from the ring nut to the choking member is achieved by a mechanism comprising a plurality of toothed gears.

  • Patent number: 9383033
    Abstract: An automatic balancing valve is described provided with a valve body having at least one inlet channel and an outlet channel for a heat transfer fluid, wherein the flow regulation is carried out by a ball shutter having an axial through channel with axis perpendicular to the rotation axis of the ball. The ball valve has at least one radial channel aligned with the rotation axis of the ball and is connected to the axial through channel. The radial channel has an outlet port having a circular cross-section which hydraulically connects the axial through channel of the ball with the outlet channel of the valve.

  • Patent number: 8985140
    Abstract: An automatic balancing valve is disclosed which is equipped with choking means that can be operated manually with a ring nut placed below the actuating member of the shutter and aligned axially therewith. Advantageously, the dimensions of the ring nut are larger in plan view compared to the plan view dimensions of the actuating member so as to allow its rotation without removing the actuating member.
