Body Size and End Connection Style
1/4-inch (DN 8) NPT
Maximum Allowable Inlet Pressure
(1)
67 or 67R:
250 psig (17 bar)
67H, 67HR, 67SS, or 67SSR:
400 psig (28 bar)
Maximum Emergency Outlet Pressure
(1)
50 psig (3,4 bar) over outlet pressure setting, or
100 psig (7,6 bar), whichever is greater
1. The pressure/temperature limits in this instruction manual or any applicable standard limitation should not be exceeded.
Specifications
Outlet Pressure Ranges
3 to 100 psig (0,21 to 6,9 bar) with the springs
shown in parts list key 9
Internal Relief Performance
(Type 67HR, 67R, or 67SSR Only)
Low capacity for seat leakage only; external relief
valve must be provided if inlet pressure can exceed
maximum emergency outlet pressure

Temperature Capabilities
(1)
Nitrile (NBR):
–20° to 150°F (–29° to 66°C)
Fluoroelastomer (FKM):
0° to 350°F (–18° to 177°C)
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.
