Product Descriptions
The 67D Series direct-operated regulators are typically
used to provide constantly controlled, reduced pressures.
They are suitable for most air or gas applications.
• The Types 67D and 67DS are the standard
instrument supply regulators without a lter or
internal relief.
• The Types 67DF and 67DFS are equipped with a
lter for removing particles from the supply gas.
• The Types 67DR and 67DSR have an internal relief
valve with a soft seat for reliable shutoff with no
discernible leakage.
• The Types 67DFR and 67DFSR have a lter and
internal relief valve with a soft seat for reliable
shutoff with no discernible leakage.
Principle of Operation
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 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.

Installation
Note
If the regulator is shipped mounted on
another unit, install that unit according
to the appropriate Instruction Manual.
WARNING
!
Personal injury, property damage,
equipment damage or leakage due to
escaping gas or bursting of pressurecontaining parts may result if this
regulator is overpressured or is installed
where service conditions could exceed
the limits given in the Specications
section, or where conditions exceed any
ratings of the adjacent piping or piping
connections. To avoid such injury or
damage, provide pressure-relieving or
pressure-limiting devices (as required
by the appropriate code, regulation or
standard) to prevent service conditions
from exceeding those limits.
The internal relief valve of the
Type 67DR, 67DSR, 67DFR or 67DFSR
does not provide full overpressure
protection. The internal relief valve is
designed for minor seat leakage only. If
maximum inlet pressure to the regulator
exceeds maximum pressure ratings of
the downstream equipment or exceeds
maximum allowable outlet pressure of
the regulator, additional overpressure
protection is required.
A regulator may vent some gas to
the atmosphere. In hazardous or
ammable gas service, vented gas may
accumulate and cause personal injury,
death or property damage due to re or
explosion. Vent a regulator in hazardous
gas service to a remote, safe location
away from air intakes or any hazardous
area. The vent line or stack opening
must be protected against condensation
or clogging.
Before installing a Type 67D, 67DR, 67DS, 67DSR,
67DF, 67DFR, 67DFS or 67DFSR regulator, be
sure the installation complies with the following
installation guidelines:
1. Regulator operation within ratings does not
preclude the possibility of damage from debris
in the lines or from external sources. Regulators
should be inspected for damage periodically and
after any overpressure condition.
2. Only personnel qualied through training and
experience should install, operate and maintain
the regulator. Make sure that there is no damage
to or foreign material in the regulator. Also ensure
that all tubing and piping is free of debris.
3. Install the regulator so that ow is from the IN to the
OUT connection as marked on the regulator body.
4. A clogged spring case vent hole may cause the
regulator to function improperly. To keep this
vent hole from being plugged (and to keep the
spring case from collecting moisture, corrosive
chemicals or other foreign material) orient the vent
to the lowest possible point on the spring case or
otherwise protect it.
