Introduction
Scope of Manual
This manual describes and provides instructions and
parts lists for the Type 67, 67H, 67HR, 67R, 67SS, and
67SSR regulators without filters. These regulators
usually are shipped separately for line or panel mount-
ing, although sometimes they are shipped installed on
other equipment. Instructions and parts lists for other
equipment, as well as for other 67 Series regulators not
covered in this manual, are found in separate manuals.
Product Description
Type 67, 67H, 67HR, 67R, 67SS, and 67SSR self-
operated, small-volume regulators (figure 1) provide
constant reduced pressures in a variety of applications.
Although most of these regulators may be used only
with air or other gases, or certain liquefied gases, those
with brass or stainless steel bodies additionally may be
used for water and similar liquid service.
A Type 67HR, 67R, or 67SSR regulator has an integral
low-capacity internal relief valve. In these constructions,
the stem seats against a soft-seated orifice in the
diaphragm assembly. A downstream pressure increase
above the outlet pressure setting moves the diaphragm
assembly off the stem, venting the excess pressure
through a hole drilled or tapped in the spring case.
Specifications
Table 1 gives some general Type 67, 67H, 67HR, 67R,
67SS, and 67SSR regulator ratings and other specifica-
tions. A label on the spring case gives the recom-
mended and actual control spring range for a given
regulator as it comes from the factory.

Form 5040, May 1986
The body plug on the Types 67 and 67R regulators has been redesigned. The body seal gasket and body plug
previously used on the Types 67 and 67R regulators have been replaced with a new body plug assembly. The body
plug assembly includes the body plug and the body plug O-ring. This change only effects the Types 67 and 67R.
Replace or add the following information to the Types 67, 67H, 67HR, 67R, 67SS, and 67SSR Instruction Manual,
form 5040.
• Replace the Trim Parts of the Maintenance section on page 4 with the following:
1. Remove body plug (key 3 or 3A) to let the plug spring (key 6) and plug/stem assembly (key 4) drop freely from
the body (key 1).
2. Inspect the removed parts, replace if neccessary. Make sure the plug seating surfaces are free from debris.
On Types 67 and 67R, inspect body plug O-ring (key 3B), replace if necessary. Type 67 and 67R regulators
manufactured before May 1999 need to have the body plug gasket (key 23, figure 2) and the body plug (key 3)
replaced with a new body plug assembly (key 3), which includes the body plug (key 3A) and the body plug O-ring
(key 3B). On Types 67SS and 67SSR, inspect the body plug O-ring (key 23, figure 3), replace if necessary.
3. Install the body plug O-ring (key 3B, figure 2 or key 23, figure 3) over the body plug (key 3A, figure 2 or key 3,
figure 3).
4. Stack the plug spring (key 6) and the plug/stem assembly on the body plug (key 3A, figure 2 or key 3,
figure 3), and install the body plug with stacked parts into the body (key 1).

Installation
Personal injury, property damage, equip-
ment damage, or leakage due to escap-
ing gas or bursting of pressure-containing
parts may result if this regulator is over-
pressured or is installed where service
conditions could exceed the limits given
in the Specifications 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. A Type 67HR, 67R, or 67SSR
regulator, because of its low-capacity
internal relief, does provide very limited
downstream overpressure protection, but
it should not be considered complete
protection against overpressure.
Additionally, physical damage to the
regulator could cause personal injury or
property damage due to escaping gas.
To avoid such injury or damage, install
the regulator in a safe location.
Regulator operation within ratings does not preclude
the possibility of damage from debris in the lines or
from external sources. A regulator should be inspected
for damage periodically and after any overpressure
condition.
Note
If the regulator is shipped mounted on
another unit, install that unit according
to the appropriate instruction manual.
1. Only personnel qualified through training and
experience should install, operate, and maintain a
regulator. For a regulator that is shipped separately,
make sure that there is no damage to, or foreign
material in, the regulator. Also ensure that all tubing and
piping have been blown free.
2. Install the regulator so that flow through it is from IN
to OUT as marked on the regulator body. Panel-mount-
ing cutout dimensions are shown in figure 2 for a Type
67, 67H, 67HR, or 67R regulator and in figure 3 for a
Type 67SS or 67SSR regulator.

Types 67, 67H, 67HR, 67R, 67SS, and 67SSR

A regulator may vent some gas to the
atmosphere. In hazardous or flammable
gas service, vented gas may accumulate
and cause personal injury, death, or
property damage due to fire or explo-
sion. 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.
3. 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, and other
foreign material) orient the vent to the lowest possible
point on the spring case or otherwise protect it. Inspect
the vent hole regularly to make sure it has not been
plugged. Spring case vent hole orientation may be
changed by rotating the spring case with respect to the
regulator body. A Type 67, 67H, 67HR, 67R, 67SS, or
67SSR regulator with a tapped spring case may be
remotely vented by first removing the vent screen if used
(key 47, figure 3) and installing obstruction-free tubing
or piping into the 1/4-inch NPT vent tapping. Provide
protection on a remote vent by installing a screened
vent cap into the remote end of the vent pipe.
4. For use in regulator shutdown, install upstream and
downstream vent valves or provide some other suitable
means of properly venting the regulator inlet and outlet
pressures.
5. If using pipe, apply a good grade of pipe compound
to the pipe threads before making the connections.
6. Install tubing or piping into the 1/4-inch NPT inlet
connection on the body assembly (key 1, figure 2 or 3)
and also into the 1/4-inch NPT outlet connection,
unless this connection already has been factory-piped
to another unit.
Startup and Adjustment
Key numbers are referenced in figure 2 for a Type 67,
67H, 67HR, or 67R regulator and in figure 3 for a Type
67SS or 67SSR regulator.
1. With proper installation completed and downstream
equipment properly adjusted, slowly open the upstream
and downstream shutoff valves while using pressure
gauges to monitor pressure.
2. Regulator outlet pressure may be monitored on a
gauge installed at some point downstream from the
regulator. Or, outlet pressure may be monitored on a
gauge (key 21, not shown) installed on the body of a
regulator with a tapped side outlet. If the regulator has
no gauge but the side outlet is tapped and plugged, the
pipe plug (key 21, figure 3) may be removed and a
gauge temporarily installed for monitoring.
To avoid personal injury, property dam-
age, or equipment damage caused by
bursting of pressure containing parts or
explosion of accumulated gas, never
adjust the control spring to produce an
outlet pressure higher than the upper
limit of the outlet pressure range for that
particular spring. If the desired outlet
pressure is not within the range of the
control spring, install a spring of the
proper range according to the dia-
phragm parts maintenance procedure.
Note
Each regulator is factory-set for the
pressure setting specified on the order. If
no setting was specified, outlet pressure
was factory-set at the midrange of the
control spring.
3. If outlet pressure adjustment is necessary, monitor
outlet pressure with a gauge during the adjustment
procedure. The regulator is adjusted by loosening the
locknut (key 11, if used) and turning the adjusting screw
or handwheel (key 10) clockwise to increase, or coun-
terclockwise to decrease, the outlet pressure setting.
Then tighten the locknut (if used) to maintain the
adjustment position. On some regulators, a closing cap
(key 28, figure 3) must be removed before adjustment
and replaced afterward.
Shutdown
First close the nearest upstream shutoff valve and then
close the nearest downstream shutoff valve to vent the
regulator properly. Next, open the vent valve between
the regulator and the downstream shutoff valve nearest
to it. All pressure between these shutoff valves will be
released through the open vent valve, since a Type 67,
67H, 67HR, 67R, 67SS, or 67SSR regulator remains
open in response to the decreasing downstream
pressure.

Types 67, 67H, 67HR, 67R, 67SS, and 67SSR

Maintenance
Regulator parts are subject to normal wear and must be
inspected and replaced as necessary. The frequency of
inspection and replacement of parts depends upon the
severity of service conditions and upon applicable codes
and government regulations.
If used, the inlet screen assembly (key 24, figure 3)
may need to be cleaned periodically.
To avoid personal injury, property dam-
age, or equipment damage caused by
sudden release of pressure or explosion
of accumulated gas, do not attempt any
maintenance or disassembly without first
isolating the regulator from system
pressure and relieving all internal
pressure from the regulator.
Note
If sufficient clearance exists, the body
assembly (key 1) may remain mounted in a
line or panel or on other equipment unless
the inlet screen assembly (key 24 if used,
figure 3) needs to be cleaned or replaced
or the entire regulator will be replaced.
Unless otherwise noted, key numbers are referenced in
figure 2 for a Type 67, 67H, 67HR, or 67R regulator and
in figure 3 for a Type 67SS or 67SSR regulator.
Trim Parts
1. Remove body plug (key 3 or 3A) to let the plug
spring (key 6) and plug/stem assembly (key 4) drop
freely from the body (key 1).
2. Inspect the removed parts, replace if necessary.
Make sure the plug seating surfaces are free from debris.
On Types 67 and 67R, inspect body plug O-ring (key 3B),
replace if necessary. Type 67 and 67R regulators manu-
factured before May 1999 need to have the body plug
gasket (key 23, figure 2) and the body plug (key 3)
replaced with a new body plug assembly (key 3), which
includes the body plug (key 3A) and the body plug O-ring
(key 3B). On Types 67SS and 67SSR, inspect the body
plug O-ring (key 23, figure 3), replace if necessary.
3. Install the body plug O-ring (key 3B, figure 2 or key
23, figure 3) over the body plug (key 3A, figure 2 or key
3, figure 3).
4. Stack the plug spring (key 6) and the plug/stem
assembly on the body plug (key 3A, figure 2 or key 3,
figure 3), and install the body plug with stacked parts
into the body (key 1).
Diaphragm Parts
1. Remove the closing cap if used (key 28, figure 3),
loosen the locknut if used (key 11), and back out the
adjusting screw or handwheel (key 10) until compres-
sion is removed from the control spring (key 9).
2. Remove the machine screws (key 12) and separate
the spring case (key 2) from the body assembly (key 1).
Remove the control spring seat and control spring
(keys 8 and 9).
3. Remove the diaphragm assembly (key 7) and
inspect the diaphragm.
4. Install the diaphragm assembly (key 7) and push
down on it to see if the plug/stem assembly (key 4)
strokes smoothly and approximately 1/16 inch (2 mm).
Note
In step 5, if installing a control spring of
a different range from the one that was
removed, be sure to delete the spring
range originally appearing on the
control spring label (key 20, not shown)
and indicate the new spring range.
5. Sparingly apply lubricant to the control spring seat
(key 8). Stack the control spring and control spring seat
(keys 9 and 8) onto the diaphragm assembly (key 7).
6. Install the spring case (key 2) on the body assembly
(key 1) with the vent hole oriented to prevent clogging or
entrance of moisture. Install the machine screws (key 12)
and torque to 15 to 20 inch-pounds (1,9 to 2,6 N•m).
7. When all maintenance is complete, refer to the
startup and adjustment section to put the regulator
back into operation and adjust the pressure setting.
Tighten the locknut if used (key 11).
8. With a Type67SS or 67SSR regulator, install a
replacement closing cap gasket (key 32, figure 3) if
necessary.
9. Install the closing cap if used (key 28, figure 3).
