Abstract
Disclosed is a manual balancing valve having an upstream end and a downstream end, and a first equalizing ring () and a second equalizing ring () configured at the upstream end and the downstream end, respectively. Each of the first and the second equalizing rings comprises an annular body () defined between an inner peripheral edge portion () and an outer peripheral edge portion (), an annular chamber () configured adjacent to the inner peripheral edge portion, a plurality of holes () configured on the inner peripheral edge portion and in fluid communication with the annular chamber, and a pressure tap (T) in fluid communication with the annular chamber and extending radially outward of the annular body. The first and the second equalizing rings are adapted to provide static pressure value at each of the upstream and the downstream ends so as to measure differential pressure therebetween and control the fluid flow rate through the valve.
