aiRFlex® is the only air actuated on-off valve in industry standard face-to-face dimensions (1”-60”)– aiRFlex® is a drop in replacement for other valves. The non-stretch aiRFlex® design increases elastomer tube life 2 to 3 times over conventional air-actuated pinch valves.

Versatile & Dependable Valves

aiRFlex® valves are ideal for all liquids and powders in low-pressure applications. These premium air actuated valves feature patented tube folds that minimize stretching when air is introduced between the valve body and the tube to close the valve, resulting in longer life and enhanced performance.

World Class Performance

  • Patented No-Stretch Tube Folds

    Our patented no-stretch tube design features 2 joint-like expansion arches that flex instead of stretch when closing. This unique elastomer sleeve design results in longer sleeve life.

  • SMART Valve ™ Monitoring System

    The SMART Valve ™ Wear Sensor Indicator Wire alerts maintenance personnel that the tube is worn, facilitating preventive maintenance.

  • Trouble-Free Operation, Recommended in the Toughest Applications

    The self-cleaning flexing action of the elastomer tube prevents build-up of scaling deposits and ensures the valve will not seize or jam, even with high solids.

  • In-Line and Quick Tube Change

    The RF VALVE design allows the tube or sleeve to be changed with the valve in-line, saving maintenance time and eliminating the need for recalibration.

  • ASME Standard Face-to-Face Dimensions

    Our pinch valve design allows for easy placement into a pre-existing pipeline replacing other standard valves.
