This manual provides instructions and parts lists for
67C Series instrument supply regulators. Instructions
and parts lists for other equipment mentioned in this
instruction manual, as well as for other 67 Series
regulators, are found in separate manuals.

The 67C Series direct-operated regulators are
typically used to provide constantly controlled,
reduced pressures to pneumatic and electropneumatic
controllers and other instruments. They are suitable
for most air or gas applications. Other applications
include providing reduced pressures to air chucks, air
jets, and spray guns.
• The Types 67C and 67CS are the standard
instrument supply regulators without a lter or
internal relief.
• The Types 67CF and 67CFS are equipped with a
lter for removing particles from the supply gas.
• The Types 67CR and 67CSR have an internal
relief valve with a soft seat for reliable shutoff with
no discernible leakage.
• The Types 67CFR and 67CFSR have a lter and
internal relief valve with a soft seat for reliable
shutoff with no discernible leakage.

spring case gives the control spring range for a given
regulator as it comes from the factory.
