Abstract
A dispensing valve arrangement is provided which includes a series of pinch valves and their respective deformable hoses. A pair of actuating mechanisms is provided so that some of the pinch valves first move to full flow position before other pinch valves move towards opened position to provide sequential operation and an additional feed which confluently merges and mixes with the feed from the first valves.
