Precision internal Pilot Regulators provide improved
torque control for pneumatic tools; diaphragm type.
Pressure settings held within 3 psig (0.2 bar).
Remote Pilot Regulators use any small regulator to
provide remote adjustment and to ensure accurate
pressure control. Diaphragm type.
Reverse-Flow Regulators provide regulated in-to-out pressure control, plus
quick exhausting from out-to-in. Used for applications, such as weld guns,
requiring quick exhausting through the regulator.
IMPORTANT NOTE: Please read carefully and thoroughly all of the CAUTIONS on the inside back cover.
