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 Congurations 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
benecial for offshore applications.
• Full Usable Capacity—Fisher® regulators are
laboratory tested. 100% of the published capacities
can be used with condence.
• 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.
