Air actuated pinch valve type aiRFlex®
The ideal valve solution for isolating and regulating abrasive, corrosive and fibrous media such as granulates, powders, pellets, dusts, slurries and solid-containing liquids.
How do air actuated pinch valves work?
By supplying compressed air/fluid (differential pressure min. 2 bar) to the casing of the pinch valve, the rubber sleeve is being compressed, leading to an absolutely tight closing of the valve. Even larger solids are enclosed by the rubber sleeve and thus tightly sealed.
The unique and patented non stretch-tube design with expansion arches ensure a longer service life of the sleeve. Optionally, the sleeve can be equipped with the monitoring system "MONSYS", which alerts maintenance personnel that the tube is worn.
The maximum operating pressure of this valve is 6 bar. As soon as the supply of compressed air/liquid is interrupted and the air operated pinch valve casing is vented or drained, the rubber sleeve opens by its rebound and the medium pressure.
What are the benefits of aiRFlex® pinch valves?
100% leak free, patented tube folds, free flow of product, cavity free, wear resistant, easy to maintain (quick sleeve change with valve in-line), minimum frictional resistance, no blockages and low weight are only a few advantages to be named.
