Kuhnke 72 series micro pneumatic valves are available as either a roller lever valve, a push button valve or as an air-jet detector valve; they are miniature by design, particularly useful for applications where space is limited.
Push-button and roller lever valves have a low actuation force of 1N. Typical flow rates of up to 95 l/min at 8 bar are possible. The actuating distance of the button is only 0.6mm at 8 bar.
Air-jet detector valves are designed to sense delicate components. A stream of air is sent from a nozzle, as an object touches the air nozzle, the flow is interrupted, causing back pressure which operates the valve, the volume of tubing determines the actuation time.
The valve body is a moulded polyamide plastic material with integrated 4mm push-fit connectors. Mount the device using the two 3mm diameter through holes in the valve body.
