Manual Balancing Valves
The Flow Optimizer is a durable plastic insert that is pressed into the discharge end of the ball. The parabolic shape of the Flow Optimizer modifies valve characteristics in such a way that the valve setting becomes simple and quick. With ordinary type balance valves, the throttle characteristics of the valve are such that from full open to 20% closed, ball valves do not control flow; instead, the ball valve and flow passage is literally wide open. From 70% to 100% closed, throttling is extremely sensitive and difficult. The operator must manipulate the valve handle repetitively to achieve the desired set point.
