Kuhnke 74 series miniature valves are constructed using a light, durable zinc alloy; they are miniature by design, used where space is restricted.

Port sizes are M5 threaded; there are only two connections; the exhaust is through the body of the valve.

Pressures of up to 12 bar are possible with flow rates of up to 225 l/min. The mechanical force used to operate the valve depends upon the connected pressure, approximately 25N at 6 bar is possible.

Several operator types are available for the 74 series valve; operator types are a plunger, toggle lever, button and roller, all with a spring assisted return.
