You will find Kuhnke pneumatic valves divided into three sections of this site. On this page you can see an overview of the extensive selection of Kuhnke standard pneumatic valves. The list includes manually, mechanically, pneumatically and electrically operated valves from 1/8 to 1/2" ports. Included here are some hard to find products such as flip-flop valves, the plugs, manifolds and accessories and the Kuhnke range of ISO and NAMUR valves. Miniature valves, for example M5 ports, and the Kuhnke range of valve islands for interfacing with PLCs can be found elsewhere on this site.
