CVS Type 67AFR Filter
Regulator
Introduction
This CVS Controls product manual includes
instructions for the installation, adjustment,
maintenance and parts ordering of the CVS Type
67AFR Filter Regulator.
All CVS Controls equipment should be installed,
operated and maintained by qualified personnel. If
you have any questions regarding this equipment,
contact your CVS Controls representative.
Ensure that the label of the control spring range is
updated to reflect any changes in field equipment,
materials, service conditions or pressure settings.
If any venting occurs or a leak develops in the
pressure system this indicates that service is
required. Failure to remove the regulator from
service for immediate maintenance may cause a
hazardous situation.
These regulators are often shipped installed on
other equipment. Information on that equipment
will be contained in separate manuals.
Description
The CVS Type 67AFR Filter Regulator is a self-
operated unit which provides continuous reduced
pressures in a variety of applications and service
conditions. Common use is as supply pressure
regulators for pneumatic instruments.
A cellulose filter is used with the CVS Type 67AFR
Filter Regulator and will remove particles greater
than 0.0016 inch (0.040 mm) in diameter.
In addition, these regulators contain integral low-
capacity relief valves. In this type of construction

sits against an orifice in the diaphragm assembly.
When downstream pressure increases above the
set point, the diaphragm assembly moves off the
valve stem and excess pressure is vented through
a port hole tapped in the spring case.
Installation
Warning
Do not install any pressure equipment where
service conditions exceed the manufacturer's
specifications. Over pressuring of regulator
may result in leakage, equipment damage or
injury. Excessive pressure can cause the
pressure-containing parts to burst, or
accumulated gas to explode. The CVS Type
67AFR Filter Regulator cannot be used with
hazardous gas unless vented to a safe area.
