CVS 67CFR Regulator with optional gauge
Instrument Supply Regulator
INTRODUCTION
The CVS Controls 67CFR Filter regulator is a
pressure reducing supply regulator typically used
for pneumatic and electro-pneumatic controllers,
as well as other instrumentation equipment. The
CVS 67CFR provides constant, clean air or gas
supply to devices requiring reduced pressures for
control.
These Installation Instructions provide installation
and Start Up procedures for the CVS 67CFR
Regulator. Should additional maintenance or part
information be required, please refer to the
CVS 67 CFR Instruction Manual.

INSTALLATION
It is recommended that only qualified or authorized
personnel install and maintain the CVS 67CFR
regulator.
Prior to installing, make sure there is no damage to
the regulator, as well as foreign debris in all tubing
or piping connections to the installation.
Ensure proper safety procedures are adhered to
during installation and maintenance.
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 67CFR Filter Regulator should not be used
with hazardous gas unless vented to a safe area.
3. Prevent plugging of the spring case vent and
keep the spring case from collecting moisture,
corrosive chemicals or other materials by
orienting the vent to the lowest possible
point on the spring case. For panel mounted
vented installations, the 1/4" NPT spring case
vent may be remotely vented by installing
tubing or piping.
4. To change the filter/drain orientation, rotate
the filter cap with regards to the regulator
body. Change the spring case/vent
orientation by rotating the spring case in
relation to the regulator body.
Warning
Never adjust the control spring to produce pressure beyond
its highest outlet pressure range. Over pressuring the spring
can cause bursting of pressure containing parts, or explosion
of accumulated gas. If the range of the control spring does
not reach the desired outlet pressure install a spring with
the proper range according to the maintenance section.
The CVS 67CFR regulators internal relief valve does
not provide overpressure protection. The internal
relief valve is designed for minor seat leakage only.
Additional overpressure protection may be
required should the inlet pressure exceed the
maximum pressure rating of the downstream
equipment, or maximum allowable outlet.
Periodically inspect the regulator for damage, and
after an overpressure condition. Remove from
service and replace or maintain the regulator as
required.
1. Install the regulator so that the direction of
flow is from the IN to the OUT, as marked on
the regulators housing.
2. For best drainage, install the regulator so that
the drain valve (12) is at the lowest possible
point.
5. Suitable means of venting the regulator inlet
and outlet pressures for regulator shutdown
may be achieved by installing upstream block
and vent valves and downstream block and
vent valves if required.
6. Apply pipe compound or suitable Teflon tape
to the male pipe threads prior to making
connections, take care not to get excess pipe
compound inside piping or regulator.
7. Install 1/4" NPT supply tubing or pipe fitting
to the inlet of the regulator body marked
“IN”. Proceed to install 1/4” tubing or pipe
fitting to the other side of the regulator body
marked “OUT”.
8. The additional 1/4" NPT outlet may be used
for an optional CVS pressure gauge. If a gauge
is not being utilized, a 1/4" NPT plug must be
used.
9. Should the CVS 67CFR regulator be installed
in an existing installation, it may be necessary
to install spacers on the mounting bolts to
adapt to the installation. If mounting bolts are
too long place a spacer on the mounting bolt
and ensure at least two full threads of
engagement.

START UP AND ADJUSTMENT
1. Once installation is complete and
downstream equipment is properly adjusted,
slowly open the supply and downstream
shutoff valves (if installed) while using
pressure gauges to monitor supply and outlet
pressure.
2. Should outlet pressure adjustment be
required, install and monitor outlet pressure
using a gauge during the start-up procedure.
The CVS 67CFR regulator outlet pressure can
be raised or lowered by loosening the locknut
(10), and turning the adjustment screw (3),
clockwise to increase outlet pressure, or
counter clockwise to decrease outlet
pressure.
3. Tighten the locknut (10) one the desired
outlet pressure has been properly set as
required.
4. Periodically inspect the regulator for signs or
wear or damage, and repair or replace as
necessary.
For more information or questions, please
contact a CVS Controls representative.
