MID-SIZE Regulators

FEATURES:

• Modular or inline mounting

• Piston-type design

• Self-relieving; optional non-relieving

• Pressure gauge

• Adjustment knob is removable for tamper-resistance

C

Reverse-Flow Regulators are also available. They provide regulated
in-to-out pressure control, plus quick exhausting from out-to-in.

B

Used for downstream pressure regulation of weld guns and other
applications requiring quick exhausting through the regulator.

Available with adjustment knob or T-handle.

Precision internal Pilot Regulators provide improv ed
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.
