Thumb Operators

Thumb Operator are used on push button control valves to provide a larger tactile actuation surface and reduce operator fatigue.  A unique acetal pad minimizes side load and virtually eliminates wear.  The Thumb Operator is manufactured from steel and electroless nickel plated for corrosion resistance.  Not recommended for use with Pneumadyne’s “4” Series valves.
