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.
