2083838 9119124 PCTABS00008 An adjustable control valve for flow regulation of gas or liquid has a controlled hose clamp device, preferably with two clamping members (K1, K2) disposed on respective sides of a hose (A) for adjustable compression of the hose and thereby setting of the flow cross-section of the hose at a compression site between the clamping members. The control valve comprises further a movable cam disk, e.g. a rotatable eccentric sheave (E), actuated by a shifting mechanism, preferably a step motor, disposed for variable compression of the hose in accordance with the position of the cam disk or eccentric sheave. For automatically controlled setting of the flow cross-section of the hose, the shifting mechanism may be arranged to be controlled from measuring means mounted for gauging the flow in the hose (A) downstream of the compression site (As). In practice such regulation may be used for controlling the quantity ratios between the supplies of paint, jet formation air and atomizing air, respectively, to an atomizing gun (P), preferably by means of a common data processing unit (D) inserted between the control valve (Sa, Sp, Sf) and measuring means (Ma, Mp, Mf) in all control loops (Qa, Qp, Qf) for the supplies of paint, jet formation air and atomizing air, respectively, to the spray gun (P).
