The Brand, adjustable proportional flow divider comes in three basic models FP53, FP55 and FP56. The FP series receives a single stream of fluid and divides it into two streams. The customer has the ability to adjust one (FP53 or FP55) or both (FP56) outlet flows. The initial flow settings will not fluctuate even though the work being done by one of the streams is much greater than the work being done by the other. The ratio of the outlet streams remains constant even when the inlet flow increases or decreases.
