Introduction
Scope of the Manual
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 67C Series
regulators, are found in separate manuals.
product Descriptions
The 67C Series direct-operated regulators are typically
used to provide constantly controlled, reduced
pressures to pneumatic and electro-pneumatic
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 filter or
internal relief.
Figure 1. 67C Series Regulators
• The Types 67CF and 67CFS are equipped with a
filter 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 filter and
internal relief valve with a soft seat for reliable
shutoff with no discernible leakage.
principle of operation
Downstream pressure is registered internally on the
lower side of the diaphragm. When the downstream
pressure is at or above the set pressure, the valve plug
is held against the orifice and there is no flow through
the regulator. When demand increases, downstream
pressure drops slightly allowing the spring to extend,
moving the stem down and the valve plug away from
the orifice. This allows flow through the regulator.
