66 Series Direct-Operated Regulators and
Vacuum Service Equipment
W1935/IL
Figure 1. Exterior of Type 66 or 66Z Regulator
Introduction
Fisher® 66 Series direct-operated pressure-reducing
regulators are widely used in burner control, tank
blanketing systems, and other applications where
precise control of low-pressure industrial gases is
needed, while 66 Series direct-operated vacuum service
equipment comes in both vacuum regulator and vacuum
breaker constructions. These products differ in pressure
capabilities and construction (Figures 1 through 4).
Features
• Sensitive Response to Pressure Changes—
Minimum lockup at high as well as low inlet
pressures is provided on all regulators by a balancing diaphragm that reduces unbalanced forces acting on valve plug.
• Tank Blanketing Capability—Maximum
sensitivity and low outlet pressure accuracy
make this an ideal regulator for tank blanketing (padding) applications.
• Accuracy—Pitot tube of Type 66, 66Z, or 66ZZ standard cast iron regulator registers body outlet pressure from point of highest velocity, creating a dynamic boost (Figure 5 or 6) that helps provide a more nearly constant downstream pressure and rapid adjustment to small demand changes.
• Application Flexibility—Steel and stainless steel bodies are available for increased resistance to piping stresses or whenever dictated by local codes. External registration is standard or optional depending on construction for wherever a remote control line is required.
D100114X012
• Seat Protection without Sacrifice in Shutoff Capability—Retainer (Figure 2) of standard Type 66, 66Z, or 66ZZ valve plug assembly closes against the orifice before assembly can over travel and thus over-compress O-ring.

Figure 2. Types 66, 66Z, and 66ZZ Construction Details
Available Configurations
Constructions come standard with cast iron bodies
and pitot tube style internal registration that eliminates
the need for control line piping. Steel-body regulators
also are available and come standard with a tapped
connection boss on the diaphragm case for external
registration that requires a separate control line.
Vacuum regulators and breakers in this series come
standard with a tapped connection boss on the
diaphragm case for external registration that requires
a separate control line.
The vacuum regulators are used to prevent a
decrease in vacuum (increase in absolute pressure).
A decrease in the controlled vacuum opens the
regulator, allowing higher vacuum at the outlet to
restore the controlled vacuum to setpoint.

W0041-1*/IL
standard type 66ZZ regulator with internal registration
The vacuum breakers are used in applications where
a vacuum must be limited. An increase in vacuum
(decrease in absolute pressure) opens the breaker,
allowing atmospheric pressure or lower vacuum to
restore the controlled vacuum to setpoint.
Types 66 and 66ZZ regulators both use a single
control spring, but the Type 66ZZ regulator’s spring
has a low rate of tension and can be stretched
between the adjusting screw and valve plug stem
to enable outlet settings slightly below atmospheric
pressure and even more sensitive regulation than is
available with the Type 66 regulator. The Type 66Z
regulator uses an additional spring under the valve
plug and disk assembly to counter the control spring
effect and balance the weight of the internal parts,
thus permitting below-atmospheric settings with a
more compact construction than is available with the
Type 66ZZ regulator.

Figure 3. Standard Steel Body Operational Schematic
Principle of Operation
In the cast iron Type 66 regulator, a pitot tube
senses outlet pressure. In a steel Type 66 regulator,
an external control line senses outlet pressure.
Both pressure-sensing methods register the outlet
pressure under the main diaphragm. When increased
downstream demand lowers the outlet pressure, the
lower pressure under the main diaphragm causes
the regulator main spring and valve plug and stem
assembly to open the regulator orifice and to supply
more gas to the downstream system.
When decreased downstream demand raises the
outlet pressure, the higher pressure under the
main diaphragm opposes the regulator main spring
causing the valve plug and stem assembly to close
the regulator orifice and to supply less gas to the
downstream system.
The Types 66Z and 66ZZ regulators are identical
to the Type 66 regulator in operation but different in
construction. The Type 66Z regulator has a counter
spring under the valve plug and disk assembly which
counters the main spring force to allow settings below
atmospheric pressures. The Type 66ZZ regulator has
a longer spring case where the main spring, a low
rate tension spring, is stretched between the adjusting
screw and the valve plug stem, also providing below
atmospheric settings and more sensitive pressure
regulation than the Types 66 and 66Z regulators.

Bulletin 71.1:66
Installation
A 66 Series regulator or breaker should be installed
horizontally with the diaphragm casings vertical
above the body. Other orientations will change the
setpoint and outlet pressure range due to the weight
of the internal parts. Typical installations are shown
in Figures 8 through 10.
To obtain the maximum flow capacities in some
instances, outlet piping will have to be swaged up
above the body sizes.
Connection locations and dimensions are both shown
in Figure 11.
Overpressure Protection
66 Series pressure-reducing regulators, vacuum
regulators, and vacuum breakers have different inlet
and outlet pressure ratings. Complete downstream
overpressure protection is needed whenever the
maximum allowable inlet pressure can exceed the
outlet pressure rating, and upstream protection for a
66 Series vacuum regulator additionally is needed if
there is any chance of a vacuum greater than 8 psi or
16.3-inches of mercury (0,55 bar differential) occurring
at the inlet of this kind of regulator.
Overpressuring any portion of a regulator, breaker,
or associated equipment may cause leakage,
part damage, or personal injury due to bursting of
pressure-containing parts, explosion of accumulated
gas, or implosion due to excessive vacuum.
Regulator or breaker operation within ratings does
not preclude the possibility of damage from external
sources or from debris in the pipeline. A regulator or
breaker should be inspected for damage periodically
and after any overpressure condition.
Capacity Information
Table 4 gives Type 66 and Table 5 gives Type 66Z
natural gas regulating capacities at selected inlet
pressures and outlet pressure settings. Flows are in
SCFH at 60°F and 14.7 psia (and in Nm³/h at 0°C and
1,01325 bar) of 0.6 specific gravity natural gas.
To determine equivalent capacities for air, propane,
butane, or nitrogen, multiply Table 4 or 5 capacity by
the following appropriate conversion factor: 0.775
for air, 0.628 for propane, 0.548 for butane, or 0.789
for nitrogen. For gases of other specific gravities,
multiply the given capacity by 0.775 and divide by the
square root of the appropriate specific gravity. Then,

Construction Details
if capacity is desired in normal cubic meters per hour
(Nm3/h) at 0°C and 1,01325 bar absolute, multiply
SCFH by 0.0268.
For service conditions where the pressure drop
across the regulator is less than the critical pressure
drop, (absolute outlet pressure greater than onehalf the absolute inlet pressure), use the sizing
nomographs in Fisher® Catalog 10, or the Fisher
sizing program. (Use C1 = 35)

note:
Flows are in SCFH at 60°F and 14.7 psia (and in thousands of Nm³/h at 0°C and 1,01325 bar) of air. FOR EQUIVALENT FLOWS OF OTHER
GASES, DIVIDE BY THE SQUARE ROOT OF THE APPROPRIATE SPECIFIC GRAVITY. THEN, IF CAPACITY IS DESIRED IN NORMAL CUBIC METERS PER
HOUR (Nm3/h) AT 0°C AND 1,01325 bar ABSOLUTE, MULTIPLY SCFH BY 0.0268. EACH CURVE REPRESENTS SETTING POINT OF 1-INCH W.C. (2,50 mbar)
