Interflow is a transient effect that occurs on valves of flow size 1 or 2 (26.5 lpm or 38 lpm). It
occurs as the valve is moved between positions. During this time a small flow from ports A, B and
P to port T is possible. This can cause the pressure of lines A, B or P to drop slightly. Note that
interflow will not occur when the valve is fully seated in either the centre, left or right positions.
The magnitude of interflow is highly dependent upon the valve's operating conditions and speed
of actuation hence it is difficult to predict. If no pressure drop during actuation is permissible
then a non-interflow valve should be selected (flow size 0 - 15 lpm).
The interflow range varies with the valve size (see table below).
