NEW AIR VALVE The new “ULTRA SOFT FLOW” is a servo-controlled air valve, patented and exclusive to SAGOLA, which reduces up to 65% the fatigue produced by pulling the trigger. An unprecedented ergonomic innovation that represents a substantial improvement in the working conditions of the industrial painter. The drastic reduction of the tightening force helps to prevent diseases derived from the activity itself such as tendinitis or lateral epicondylitis (tennis elbow). And it also supposes an optimization of the production processes by simplifying the painting processes: Better access to difficult areas, greater maneuverability, etc... The new ULTRA SOFT FLOW air valve design, patented by Sagola, consists of a servo-assisted piston that presses the fluid needle spring, reducing the force applied to the trigger by more than half. Available for the pressure versions of the Mini Xtreme and the X 4100 Series. Can be purchased as a kit to upgrade guns of these models with standard valve
