Abstract

A valve system has an apparatus formed with a plurality of material inlet ports, a flushing inlet port, and an outlet port and respective supplies of at last two different liquid materials. The supplies are each connected to a respective one of the material inlet ports, and a supply of flushing medium is connected to the flushing inlet port. A rotor at the apparatus is formed with a passage and shiftable between a plurality of positions in each of which a respective one of the inlet ports is connected to the outlet port. A controller moves the rotor between the positions such that, after each time the rotor is in a position connecting one of the material inlet ports to the outlet port and material has passed through the passage, the rotor is moved into a position connecting the passage with the flushing inlet port for flushing out the passage.
