Mechanically Operated Valves

Kuhnke’s mechanically operated power valve selection is available in 2, 3 or 4 way valve designs with a variety of operators including flat levers, plungers, roller levers (limit switch) and antenna versions. Some units are equipped with valve operators on both ends and with pneumatic resets.

Valves are available in standard mechanical designs or in air piloted assist versions for low actuation force applications. Valves are constructed from zinc or aluminum die cast and machined bodies. Porting can be with either NPT or Metric threads to meet connection preferences. Mechanically operated valves can be either spool or poppet designs depending on valve selection.
