Kuhnke 72 Series Micro Valves - Roller Lever, Button and Air Jet Actuated.
The Kuhnke 72 series micro pneumatic valve is designed for use in confined spaces. The main body is constructed of a moulded polyamide plastic material, the convenient 4mm push-in fittings are constructed of brass.
The push button has a particularly low actuation force of only 1N and offers flow rates of up to 95 l/min. The actuating distance of the button is only 0.6mm at 8 bar. To achieve a light actuation force, these valves will consume approximately 0.7 l/min in either the button rest position (normally closed versions), or the button actuated position (normally open versions). Push button and roller lever valves are available with a 3/2 way normally open or closed valve function, air jet detector valves are only available as normally closed.
Air jet detector valves are used for the contact sensing of parts and tools, they are often used for the sensing of delicate components. A stream of air is sent from a nozzle, as an object touches the nozzle the stream is blocked causing back pressure which operates the valve.
