Features
•Compact—The 67C Series regulators are engi-
neered for outstanding performance in a compact,
light-weight package.
•Panel Mounting—Panel mount construction
includes spring case with 1/4-inch NPT vent,
handwheel adjusting screw, and mounting nut.
•Instrument Supply Regulator—The Types 67CF,
67CFR, 67CFS, and 67CFSR provide a clean air
supply to a variety of pneumatic and electro-pneumatic
instrumentation.
•Digital Instrument Supply Regulator—Designed
for the accuracy, repeatability, and hysteresis de-
mands of digital instrumentation.
•Pilot Supply Regulator—Improves the accuracy
of two-path control regulators by reducing inlet sensi-
tivity caused by fluctuating inlet pressures.
•Pressure Loading Regulator—Provides accuracy
and improved performance in dirty steam service by
eliminating the need for a pilot regulator (see figure 3).
•Sour Gas Service Capability—NACE MR0175 and
MR0103 compliant construction available.
•Optional Stainless Steel Construction—The
Types 67CS, 67CSR, 67CFS and 67CFSR provide high
resistance to corrosion especially beneficial in offshore
applications.
•Full Usable Capacity—Fisher regulators are
laboratory tested. 100 percent of the published
capacities can be used with confidence.
•Internal Relief—The Types 67CR, 67CSR, 67CFR,
and 67CFSR have an internal relief valve with a soft
seat for reliable shutoff with no discernible leakage.
These regulators are recommended for conserving
plant air.
•Smart Bleed™—Opens to exhaust downstream
pressure when inlet pressure drops below outlet
pressure. Recommended for deadend service.
•Integral Filter—The Types 67CF, 67CFR, 67CFS,
and 67CFSR have an integral filter ensuring clean
downstream air supply.
•Ease of Maintenance—No special tools are
required to perform maintenance, and all maintenance
can be performed with the regulator in the line. Filter
elements are easily replaced. The one-piece valve
plug cartridge allows easy inspection and replacement.
•Rugged Construction—The 67C Series regulators
are engineered for longer service life with minimal
maintenance requirements.
•Second Outlet—Body side outlet for pressure
gauge or other uses.
•Powder Paint Coating—Types 67C, 67CR, 67CF,
and 67CFR are powder paint coated, offering impact,
abrasion, and corrosion resistance. Stainless steel
regulators (Types 67CS, 67CSR, 67CFS and 67CFSR)
are not painted.
•Corrosion Resistant Fasteners—Bolting and
adjusting screw are double zinc-chromated for en-
hanced corrosion resistance. Optional stainless steel
bolting and adjusting screw are also available.
Introduction
The 67C Series regulators are typically used to provide constantly controlled, reduced pressures to pneumatic and
electropneumatic controllers and other instruments. These direct-operated regulators are suitable for most air or
gas applications. Other applications include providing reduced pressures to air chucks, air jets, and spray guns.

Principle of Operation (figure 2)
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.
Internal Relief (Types 67CR, 67CSR,
67CFR, and 67CFSR)
If for some reason, outside of normal operating
conditions, the downstream pressure exceeds the set
point of the regulator, the force created by the
downstream pressure will lift the diaphragm until the
diaphragm is lifted off the relief seat. This allows flow
through the token relief. The relief valve on the
Type 67CR, 67CSR, 67CFR, or 67CFSR is an elastomer
plug that prevents leakage of air from the downstream
to atmosphere during normal operation, thereby
conserving plant air.
Smart Bleed™ Airset
In some cases, it is desired to exhaust downstream
pressure if inlet pressure is lost or drops below the
setpoint of the regulator. For example, if the regulator is
installed on equipment that at times has no flow
demand but is expected to backflow on loss of inlet
pressure. The Type 67CFR can be ordered with the
Smart Bleed™ option which includes an internal check
valve for this application. During operation, if inlet
pressure is lost, or decreases below the setpoint of the
regulator, the downstream pressure will back flow
upstream through the regulator and check valve. This
option eliminates the need for a fixed bleed downstream
of the regulator, thereby conserving plant air.
Overpressure Protection
The 67C Series regulators have maximum outlet
pressure ratings that are lower than their maximum
inlet pressure ratings. A pressure relieving or pressure
limiting device is needed if inlet pressure can exceed
the maximum outlet pressure rating. Refer to the
Capacity Information section and the Wide-Open
Coefficients for Relief Valve Sizing in the Specifica-
tions on page 3 to determine the required relief valve
capacity.
Type 67CR, 67CSR, 67CFR, and 67CFSR regulators
have a low capacity internal relief valve for minor seat
leakage only. Other overpressure protection must be
provided if the maximum inlet pressure can exceed the
maximum pressure rating of the downstream equipment
or exceeds maximum outlet pressure rating of the
Type 67CR, 67CSR, 67CFR, or 67CFSR regulator.
Capacity Information
Table 3 shows the air regulating capacities of the
67C Series regulators at selected inlet pressures and
outlet pressure settings. Flows are shown in scfh
(at 60°F and 14.7 psia) and in m³/h(n) (at 0°C and
1,01325 bar) of air.
Note
The 67C Series regulators may be sized
for 100% flow using capacities as shown
in table 3. It is not necessary to reduce
published capacities.
To determine the equivalent capacities for other gases,
multiply the table capacity by the following appropriate
conversion factor: 1.29 for 0.6 specific gravity natural
gas, 0.810 for propane, 0.707 for butane, or 1.018 for
nitrogen. For gases of other specific gravities, divide
the table capacities by the square root of the appropri-
ate specific gravity. To find wide-open flow capacities
for relief sizing at any inlet pressure, perform one of
the following procedures. Then, if necessary, convert
using the factors provided above.
For critical pressure drops (absolute outlet pressure
equal to or less than one-half of absolute inlet pres-
sure), use the following formula:
Q = (P1)(Cg)
For pressure drops lower than critical (absolute
outlet pressure greater than one-half of absolute inlet
pressure), use the following formula:

where,
Q = gas flow rate, scfh
P1= absolute inlet pressure, psia (P1gauge + 14.7)
Cg= gas sizing coefficient
G = specific gravity of the gas
T = absolute temperature of gas at inlet, °Rankine
C1= flow coefficient (Cg÷ Cv)
∆P = pressure drop across the regulator, psi
Then, if capacity is desired in normal cubic meters per
hour (at 0°C and 1,01325 bar), multiply scfh by 0.0268.

Table 3. Capacities
670 Series Panel-Mounted Loading
Regulators (figure 4)
The 670 Series panel-mounted loading regulators are
compact, rugged units used primarily for manually
loading pressure-balanced gas regulators and providing
manual control for diaphragm actuator control valves.
Applications include remote control of gas pressure to
burners in refineries, power plants, and various
process furnaces.
Three basic panels are available within the product
line, each having one 67C Series pressure regulator
connected to one or two gauges and a changeover
valve. A single gauge typically shows loading
pressure to the control valve. For more information
see bulletin 62.3:670.
Ordering Information
When ordering, complete the Ordering Guide on page
12. Refer to the Specifications on page 3. Review the
