Kuhnke 79 & 81 Series Miniature Valves - Electrically Operated.
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.
Steel spool valves are offered as a 3/2 way single solenoid, or as a 5/2 way single or double solenoid control valve. Connection port sizes are M5. Steel spool valves are supplied complete with coils. Standard operating voltages are 12V DC, 24V AC/DC or 230V AC, others voltages can also be ordered. Connecting plugs are purchased separately, these can be found in the associated products section.
