Installation, operation and maintenance
procedures performed by unqualified
personnel may result in improper
adjustment and unsafe operation. Either
condition may result in equipment
damage or personnel injury. Use qualified
personnel when installing, operating and
maintaining the 133 Series regulators.
If a leak develops in the system, the
escaping gas may accumulate and
become a fire or explosion hazard.
Immediately call qualified service
personnel in case of trouble.
Scope of Manual
This manual provides specifications, instructions
for installation, adjustment, maintenance, and parts
information for the 133 Series.
Figure 1. 133 Series Gas Regulators
Only personnel qualified through training or experience
should install, operate and maintain this regulator. If
there are any questions concerning these instructions,
contact your local Sales Office before proceeding.
Description
The 133 Series self-operated gas regulators, shown
in Figure 1 are primarily designed for industrial and
commercial applications supplying gas to furnaces,
burners and other appliances. The 133 Series
balancing system enables the regulator to provide
accurate control gas pressure for maximum combustion
efficiency despite varying inlet pressure conditions. The
single port construction provides bubble tight shutoff.
An external downstream control line is required for
the operation of the regulator. A restriction collar is
available to reduce the flow capacity of the regulator.
