Warning: Jordan Valve Control Valves must only be used, installed and repaired in accordance with these Installa­tion & Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event
of leakage or other malfunction, call a qualified service person; continued operation may cause system failure or
a general hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized fluid. Before disassem­bling a valve, be sure to release all spring tension.

IntroductIon

These Installation Instructions provide installation and
Start Up procedures for the Mark CFR Regulator.

InstallatIon

It is recommended that only qualified or authorized
personnel install and maintain the Mark CFR 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
specications. 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 Mark CFR Filter Regulator should not
be used with hazardous gas unless vented to a safe
area.

The Mark CFR 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.

Mark CFR Series Supply Regulators

2. For best drainage, install the regulator so that
the drain valve (12) is at the lowest possible
point.

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.

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 connec
tions, 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 Jordan Valve pressure gauge. If a
gauge is not being utilized, a 1/4" NPT
plug must be used.

9. Should the Mark CFR regulator be installed
in an existing installation, it may be nec-
essary 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.

startup 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 Mark CFR 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.

Jordan Valve Representative.
