Kuhnke 79 & 81 Series Pneumatic Valves - Button, Roller Ball and Whisker Operated.
Several operator types are available for the Kuhnke 79 and 81 series valve. Within this section we offer button, roller Ball and the whisker versions, available as a normally closed 3/2 way valve, or a 5/2 way valve configuration.
A characterised feature of this type of valve is a hardened, cut stainless steel spool and sleeve. The spool and sleeve are mated together during the machining process to create a precision fit. A light lubricating oil allows the spool to slide effortlessly within the sleeve, no seals are required therefore a mechanical life expectancy averaging 100 million cycles can be achieved. Valves are highly reliable when used within clean environments; they are particularly suited for use in medical, dentistry and laboratory equipment.
