MECHANICAL Foot Pedal/Treadle Valves

Foot pedal/treadle models are operated with a foot pedal/treadle that shifts the spool. The standard treadle position for a 3-position valve is the center of the valve (Position "B"). To fully shift the valve, the pedal/treadle is stepped on towards the operator (Position "A") or the treadle may be stepped on away from the operator (Position "C"). On 2-position valves, there is no positive detent for centering the spool (Position "B").
User must assume full safety responsibility for the use of foot valves. Guards are recommended and may be ordered as optional extras for certain models.
