67C Series instrument supply regulators. Instructions
and parts lists for other equipment mentioned in this
instruction manual, as well as for other 67 Series

Product Descriptions
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 applica-
tions. Other applications include providing reduced
pressures to air chucks, air jets, and spray guns.
Figure 1. Typical 67C Series Regulators
• The Type 67C and 67CS is the standard instrument
supply regulator without a filter or internal relief.
• The Type 67CF and 67CFS are equipped with a
filter for removing particles from the supply gas.
• The Type 67CR and 67CSR has an internal relief
valve with a soft seat for reliable shutoff with no
discernible leakage.
• The Type 67CFR and 67CFSR have a filter and
internal relief valve with a soft seat for reliable shutoff
with no discernible leakage.
Specifications
Some general 67C Series ratings and other
