Abstract
The disclosure relates to a coating agent valve () 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 () comprises a valve seat, a displaceable valve head (), a valve drive () for displacing the valve head () and a displaceable valve needle () which connects the valve drive () to the valve head () and moves the valve head () in correspondence with the valve drive (). The disclosure provides for an automatic reduction in pressure in order to avoid excess-pressure damage upstream from the coating agent valve ().
