Partial valve position is the feature by which the user can adjust the valve positioning of the carrier/main valve to increase or restrict the flow of water and thus allowing the increase or restriction of product flow. For example, by closing the carrier slightly (partially) you in effect allow for higher flow rate of bulk/tote input; the opposite is also true, by fully opening the carrier the bulk/tote product input flow is restricted.

Auto valve positioning is the feature by which the system itself automatically adjusts the valve position of the carrier to open and close in the most time-efficient manner.
