WARNING
!
Installation, operation and maintenance
procedures performed by unqualied
personnel may result in improper
adjustment and unsafe operation. Either
condition may result in equipment
damage or personnel injury. Use qualied
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 re or explosion hazard.
Immediately call qualied service
personnel in case of trouble.

This manual provides specications, instructions
for installation, adjustment, maintenance, and parts
information for the 133 Series.
W6803
TYPE 133HP REGULATOR
Only personnel qualied through training or experience
should install, operate and maintain this regulator. If
there are any questions concerning these instructions,
contact your local Sales Ofce 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
efciency 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 ow capacity of the regulator.

Type Number Description
Type 133H—High pressure construction for outlet
pressure range of 1.5 to 10 psig (0,10 to 0,69 bar).
The Type 133H can also use the 2-inches w.c. to
2 psig (5,00 mbar to 0,14 bar) springs of the
Type 133L. The maximum operating inlet pressure
is 60 psig (4,14 bar) with a maximum emergency inlet
pressure of 125 psig (8,62 bar).
Type 133HP—Extra high pressure construction for outlet
pressure range of 2 to 60 psig (0,14 to 4,14 bar). The
maximum operating inlet pressure rating of 150 psig
(10,3 bar) with a maximum emergency inlet pressure of
150 psig (10,3 bar).

pressure range of 2-inches w.c. to 2 psig (5,00 mbar

Figure 2. Operational Schematic of Type 133L Regulator (Also Typical of Type 133H)
Principle Operation
Refer to the operational schematics in Figures 2 and 3.
In the 133 Series, downstream pressure is registered
under the diaphragm via the external control line and
is used as the operating medium. Increased demand
lowers the downstream pressure and allows the spring
to move the diaphragm and stem assembly down,
opening the valve disk and supplying more gas to the
downstream system. Decreased demand increases
the downstream pressure and moves the diaphragm
and stem assembly up, closing the valve disk and
decreasing the gas supply to the downstream system.
Boosting System
The 133 Series incorporates a balancing diaphragm
and a boosting system. When the regulator is locked
up, inlet pressure is registered on the top of the valve
disk and on the bottom of the balancing diaphragm
through registration holes in the top of the cage. Also,
downstream pressure is registered on the bottom
of the valve disk and on the top of the balancing
diaphragm through a passage formed by grooves in
the registration disk and an annular space between the
stem and stem sleeve.
When the valve disk is open, gas ows from the inlet
over the edge of the valve disk to the outlet. Under
the valve disk near the registration disk, there is little
gas ow. The gas pressure near the registration disk
is higher than it is in the ow path where gas velocity
tends to lower the pressure. The higher pressure
near the disk is registered on the top of the balancing
diaphragm through the registration disk and the
annular space between the stem and stem sleeve.
This pressure registered on the top of the balancing
diaphragm aids downward disk travel and
compensates for spring and diaphragm effect. This
improves regulator range ability and performance.

overpressure protection is needed if the actual inlet
pressure exceeds the outlet pressure rating.
Maximum operating inlet pressure for the 133 Series
regulators is given in Table 2. All models must
be protected against inlet pressure above their
listed maximum.
Regulator operation below these emergency pressure
limitations does not preclude the possibility of damage
from external sources or from debris in the gas line.
The regulator should be inspected for damage after
any overpressure condition.
Downstream Control Line
An external downstream control line must be installed
before putting the 133 Series regulators in operation.
Without the control line, the regulator will remain wideopen. The downstream control line should be a pipe of
at least 1/2-inch (12,7 mm) diameter; connect it to the
downstream pipe line at least 5 to 10 pipe diameters
from the regulator and in a straight section of pipe.

Installation
Before installing the 133 Series regulators, inspect it
for shipping damage and be certain that the body and
orice are clean. Blow out the pipeline to remove pipe
scale and other foreign material.
The regulator may be installed in any position as long
as the ow through the body is the same as indicated
by the ow direction arrow on the body and the vent
opening is unobstructed and protected from the
entrance of rain, ice and other foreign material.
If the regulator has threaded end connections, coat
male threads with pipe compound. For anged
end connections, tighten the ange bolts evenly.
Install a three valve bypass around the 133 Series if
continuous operation is necessary.
The regulator must be protected from damage by
vehicles and other outside sources.
Overpressure Protection
The 133 Series regulators, as is the case with most
regulators, has an outlet pressure rating that is
lower than the inlet pressure rating. Some type of
The external downstream control line connection on
the Type 133HP is 1/4-inch threaded NPT.
Vent
The 133 Series vent is screened to prevent insects
or foreign material from entering. On indoor
installations, if a vent to atmosphere is required,
remove the snap ring and screen (keys 8J and 8H;
Figure 10, 11, or 12) from the Types 133H, 133L, and
133Z. Remove the Type Y602-7 screened vent and
pipe nipple (keys 50 and 49; Figure 14) from
the spring case (key 8) and pipe the vent to the
outside. The Types 133H, 133L, and 133Z have
a 1-inch NPT (internal) connection and the Type 133HP
has a 1/2-inch NPT (internal) construction.
The vent pipe should be as short as possible with
a minimum of bends and elbows. The pipe should
also have as large a diameter as possible. Install
a weather and bug resistant vent assembly on the
outside end of the vent pipe.
For indoor installation that have been piped to the
outside and for outdoor installations, the vent opening
must be positioned so that water, ice and other foreign
material cannot enter the spring case. Use care not to
place the vent opening below downspouts and eaves.
The vent opening should be checked periodically to
see that the opening has not been plugged by foreign
material. On some installations it may be necessary to
provide additional protection from the elements.

1. Pressure ranges shown are correct if the regulator is installed with the actuator portion above the body portion. If the regulator is installed with the actuator portion below the body,
the pressure ranges will be lowered by approximately 2-inches w.c. (5,00 mbar) for the Type 133L and by approximately 3-inches w.c. (7,00 mbar) for the Types 133H and 133Z.
2. If the 2-inches w.c. to 2 psig (5,00 mbar to 0,14 bar) springs (all 6 ranges) are used in the Type 133H, the pressure ranges will increase by approximately 1-inch w.c. (2,00 mbar) due
to the weight of the Type 133H parts (assuming that the actuator is installed above the body).
