Types 67CR, 67CSR, 67CFR, and 67CFSR have
a low capacity internal relief valve for minor seat
leakage only. Other overpressure protection must be
provided if the maximum inlet pressure can exceed
the maximum pressure rating of the downstream
equipment or exceeds the maximum outlet pressure
rating of the regulator.

Installation

If the regulator is shipped mounted on
another unit, install that unit according to
the appropriate Instruction Manual.

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 67CR, 67CSR, 67CFR, or 67CFSR
does not provide full overpressure
protection. The internal relief valve is
designed for minor seat leakage only. If

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 67C, 67CR, 67CS, 67CSR,
67CF, 67CFR, 67CFS, or 67CFSR 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
a 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. For best drainage, orient the drain valve (key 2) to
the lowest possible point on the dripwell (key 5). This
orientation may be improved by rotating the dripwell
with respect to the body (key 1).
