67D Series

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 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 qualified 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 flow 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.

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 pressure-
containing parts may result if this
regulator is overpressured 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.
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.
