Abstract

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