1. A mixing valve for mixing a first coating agent component with a second coating agent component of a coating agent to form a multicomponent mixture, having
a) a first coating agent inlet for supplying the first coating agent component,
b) a first coating agent valve for controlling a first coating agent flow of said first coating agent component through said first coating agent inlet,
c) a second coating agent inlet for supplying the second coating agent component,
d) a second coating agent valve for controlling a second coating agent flow of said second coating agent component through said second coating agent inlet; and
e) a coating agent outlet for discharging the multicomponent mixture in a specific outflow direction,
f) wherein the first coating agent valve and/or the second coating agent valve is designed as a rotary slide valve with two plane-parallel valve discs which are rotatable relative to one another about an axis of rotation, each of the two plane-parallel valve discs having a respective center line extending parallel to the axis of rotation, the respective center lines offset from each other perpendicular to the axis of rotation, each of the two plane-parallel valve discs having a through hole, the through holes collectively defining a valve-cross section that depends on an angle of rotation of the two plane-parallel valve discs relative to one another.
