67C Series
4
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 qualied 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 ow 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).
!
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.
