GRANULAR CHEMICALS APPLICATOR, AGRICULTURAL UNIT, PROCESS TO TRANSFER A GRANULAR CHEMICAL PRODUCT FROM A PACKAGING WITH A MINISTRATOR VALVE TO AN APPLICATION DEVICE AND THE MINISTRATOR VALVE

摘要

The method of transferring a granular chemical from a package (28) includes aligning the dispensing valve (30) with the receiving valve (24) of an application device. This dispensing valve (30) is coupled to the receiving valve and both are opened automatically when they are coupled together. They are sequenced so that the receiving valve is opened first. When the two valves are uncoupled, both are closed automatically, with the receiving valve being closed last. Granulars are wiped from the valve seats while the valves are uncoupled.
