Abstract

The system for serial application of paint or lacquer or other coating to workpieces has a control loop for regulating the pressure and/or flow rate of the color flowing through a conduit (9). A control member (2) for a parameter to be regulated is connected in the conduit. The control member is formed by a pneumatically or electrically driven valve (20) in the form of a cut-off valve. The drive unit (13) is controlled in dependence on the actual measured value of the parameter of the coating to be regulated.
