MECHANICAL Palm Button Valves
Palm button models are operated with a palm button that directly connects to the spool. The standard position of the palm button for a 3-position valve is the center of the valve (Position "B"). To fully shift the valve, the palm button is pushed away from the operator (Position "A") or pulled towards the operator (Position "C"). On 2-position valves, there is no positive lock for centering the spool (Position "B").
