Introduction

The 67D Series regulators are typically used to deliver constant reduced pressure of gaseous uids to pilot-operated
controllers and other pneumatic instrumentation. As shown in the Available Congurations table, an assortment of regulators
is available to meet diverse ow requirements.

Features

  • 

Compact—The 67D Series regulators are

engineered for outstanding performance in a
compact, lightweight package.

•  Pilot Supply Regulator—Improves the accuracy
of two-path control regulators by reducing inlet

sensitivity caused by uctuating inlet pressures.

•   Pressure Loading Regulator—Provides accuracy and
improved performance in dirty steam service by
eliminating the need for a pilot regulator.

•  Sour Gas Service Capability—NACE International MR0175
and MR0103 compliant construction available.

•  Optional Stainless Steel Construction—The
Types 67DS, 67DSR, 67DFS, and 67DFSR
provide high resistance to corrosion, which is especially

benecial for offshore applications.

•  Full Usable Capacity—Fisher® regulators are
laboratory tested. 100% of the published capacities

can be used with condence.

•  Internal Relief—The Types 67DR, 67DSR, 67DFR,
and 67DFSR 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 dead-end service.

•  Integral Filter—The Types 67DF, 67DFR, 67DFS,

and 67DFSR have an integral lter 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.

•  Rugged Construction—The 67D Series regulators
are engineered for longer service life with minimal
maintenance requirements.

•  Dual Second Outlets—Body side outlets for
pressure gauge or other uses.

•  Corrosion Resistant Fasteners—Bolting and
adjusting screw are double zinc-chromated for
enhanced corrosion resistance. Optional stainless
steel bolting and adjusting screw are also available.

Figure 2.  67D Series Operational Schematics

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 ori ce and
there is no  ow 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

ori ce. This allows  ow through the regulator.

Internal Relief 
(Types 67DR, 67DSR, 67DFR, and 67DFSR)

If for some reason, outside of normal operating conditions,
the downstream pressure exceeds the setpoint 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  ow through the token relief. The

relief valve on the Type 67DR, 67DSR, 67DFR, or 67DFSR
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  ow demand but is expected
to back ow on loss of inlet pressure. The Type 67DFR or

67DFSR can be ordered with the Smart Bleed option which
includes an internal check valve for this application. During

TYPE 67DF OR 67DFS

M1154

SMART BLEED™ OPTION FOR 

TYPE 67DFR OR 67DFSR

operation, if inlet pressure is lost, or decreases below the
setpoint of the regulator, the downstream pressure will back

 ow upstream through the regulator and check valve. This
option eliminates the need for a  xed bleed downstream of

the regulator, thereby conserving plant air.

Note

During normal operation the check valve’s metal 
to metal seat allows limited  ow through the 
regulator from the inlet to outlet, even when 
there is no downstream demand.  To prevent 
downstream pressure buildup, the Smart Bleed 
option is only avilable with the internal relief 
version of the 67 Series.

Installation

The 67D Series regulators may be installed in any position.
Spring case vents must be protected against the entrance
of rain, snow, debris, or any other foreign material that might
plug the vent openings. The inlet connection is marked “In”
and the main outlet connection is marked “Out”. If a pressure
gauge is not installed in one of the two secondary outlet
connections, plug the unused connections. See Figures 4
and 5 for dimensions.

Emerson Process Management Regulator Technologies,
Inc. provides an instruction manual with every regulator
shipped. Refer to this for complete installation, operation and
maintenance instructions. Included is a complete listing of

individual parts and recommended spare parts.

Bulletin 71.1:67D

Overpressure Protection

The 67D 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.

Types 67DR, 67DSR, 67DFR, and 67DFSR regulators have
a low capacity internal relief valve for minor seat
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 67DR, 67DSR, 67DFR, or 67DFSR regulator.

Overpressuring any portion of a regulator or associated
equipment may cause leakage, parts damage, or personal
injury due to bursting of pressure-containing parts or
explosion of accumulated gas. Regulator operation within
ratings does not preclude the possibility of damage from
external sources or from debris in the pipeline. A regulator
should be inspected for damage periodically and after any
overpressure condition.

Refer to the Capacity Information section and the Wide-

Open Flow Coefcients for Relief Valve Sizing in the
Specications section on page 3 to determine the required

relief valve capacity.

leakage only.

Note

The 67D Series regulators may be sized for 100% 
ow using capacities as  shown in Table 4.  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 specic gravity natural gas,

0.810 for propane, 0.707 for butane, or 1.018 for nitrogen.

For gases of other specic gravities, divide the table
capacities by the square root of the appropriate specic
gravity. To nd wide-open ow 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 pressure), 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:

Optional materials are available for applications handling sour
gases. These constructions comply with the recommendations
of NACE International sour service standards.

The manufacturing processes and materials used by

Regulator Technologies assure that all products specied

for sour gas service comply with the chemical, physical, and
metallurgical requirements of NACE MR0175 and/or NACE
MR0103. Customers have the responsibility to specify
correct materials. Environmental limitations may apply and
shall be determined by the user.
