Abstract: The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L1-L4), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV1), which is arranged in the first coating agent strand (L1-L4) and controls the flow of the first coating agent, wherein the first valve (SLV1) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV1), which is actuated by its own medium, is arranged in the first coating agent strand (L1-L4) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV1) exceeds a certain maximum pressure.

Abstract: The disclosure relates to a coating agent valve (1) for controlling a flow of fluid of a coating agent mixture consisting of two coating agent components (H, SL), in particular a two-component paint consisting of a master batch (SL) and a hardener (H). The coating agent valve according to the disclosure (1) comprises a valve seat, a displaceable valve head (12), a valve drive (15) for displacing the valve head (12) and a displaceable valve needle (14, 20) which connects the valve drive (15) to the valve head (12) and moves the valve head (12) in correspondence with the valve drive (15). The disclosure provides for an automatic reduction in pressure in order to avoid excess-pressure damage upstream from the coating agent valve (1).

Abstract: Various exemplary illustrations of a coating agent device are disclosed. In one example, a coating agent device may be a coating agent valve, e.g., for influencing the discharge of a coating agent. The coating agent device may include a plug-in or pluggable fastening base configured to facilitate a plug-in or pluggable mounting of the coating agent device. In some examples, the coating agent device may prevent relative rotation of the device relative to a mating component.
