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.

Principle of 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
Figure 2. Operational Schematic of Type 133L Regulator (Also Typical of Type 133H)
VALVE DISK
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

REGISTRATION DISK
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.
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.

CONTROL LINE
Downstream Control Line
WARNING
!
Downstream control line is Srequired for
proper operation of these regulators.
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 in. / 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.
The external downstream control line connection on
the Type 133HP is 1/4 NPT.
If the regulator has threaded end connections, coat
external 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 have an outlet pressure
rating that is lower than the inlet pressure rating. Some
type of 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.
Vent
The 133 Series vent is screened to prevent insects
or foreign material from entering. The Types 133H,
133L and 133Z regulators have a 1 NPT (internal)
connection and the Type 133HP has a 1/2 NPT
internal connection. If a vent to the atmosphere is
required for indoor installations, do the following:
• For Types 133H, 133L and 133Z — remove the
snap ring and screen (keys 8J and 8H, Figure 10,
11 or 12) and pipe the vent to the outside.
• For Type 133HP — remove the Type Y602-7
screened vent assembly and pipe nipple (keys 50
and 49, Figure 14) from the spring case (key 8)
and pipe the vent to the outside.
The vent pipe should be as short as possible with
minimum number of bends or elbows. The pipe should
also have the largest practical diameter. 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 be
sure that the opening has not been plugged with foreign
material. On some installations it may be necessary to
provide additional protection from the elements.

WARNING
!
If the downstream system is already
pressured by another regulator or by a
manual bypass, then extra precautions
must be taken when placing the 133 Series
in service. The outlet of the regulator must
never be subjected to pressure higher
than the inlet pressure or the balancing
diaphragm may be damaged. Also, the
control line pressure must never exceed
the set point dictated by the spring setting
by more than 3 psig / 0.21 bar or the
valve seat or diaphragm plates can be
damaged. The procedure used in putting
the regulator in service must be planned
accordingly. Pressure gauges should
always be used to monitor downstream
and control line pressures during startup.
If the downstream system is not pressured by
another regulator or by manual bypass, use the
following procedure:
1. Check to see that all appliances are turned off.
2. Slowly open the upstream shutoff valve.
3. Slowly open the downstream shutoff valve.
4. Check all connections for leaks.
5. Make nal control spring adjustments according to
the adjustment procedures.

133 Series
Adjustment
To increase the pressure setting, remove the closing
cap (key 9, Figures 10, 11, 12 and 14) and turn the
adjusting screw (key 11) clockwise; to lower the
setting, turn the adjusting screw counterclockwise.
A pressure gauge should always be used when
adjustments are being made. Do not adjust the spring
to produce an outlet pressure setting above the limit
stamped on the nameplate (key 38, not shown),
located on the casing ange. If the required pressure
setting is not within the range of the spring in use,
substitute with the correct spring. Ranges of available
springs are shown in Table 1. When changing the
spring, also change the nameplate, located on the
casing ange, to indicate the outlet pressure range.
Shutdown
Isolate the regulator from the pressure system and
release pressure from the outlet and the control line.
Inlet pressure will then automatically be released as
the regulator opens up in response to the lowered
pressure on the diaphragm.

Reassembly
Reassemble in reverse order of the above steps. When
reassembling, observe the following steps and cautions.
1. If the spring case was disassembled, reassemble
it rst. To ensure proper slack in the diaphragm
(key 15) and to facilitate reassembly of the trim
parts, tighten the casing cap screws and nuts
(keys 35 and 36) nger-tight only. Then adjust the
spring (key 12) to stroke the diaphragm assembly
fully. Final tightening of the casing cap screws and
nuts must be done alternately in equal increments
to ensure a proper seal without crushing
the diaphragm.
2. During reassembly, check all O-rings to be certain
they are in good condition; replace if necessary.
Lubricate the O-rings (keys 4, 19 and 32) with
elastomer sealant and lubricant. Apply anti-seize
compound liberally to the adjusting screw threads
(key 11), as indicated in Figures 10 to 12.
3. When installing the balancing diaphragm (key 22),
be certain the side marked PISTON SIDE is facing
the spring case. Carefully tuck the slack diaphragm
material into the space between the diaphragm
plate (key 21) and the lower casing (key 7) until the
diaphragm ts smoothly over the diaphragm plate
without wrinkles and the bead ts snugly and evenly
in the groove provided in the lower casing. This can
be done with a small screwdriver, but be careful not
to puncture the diaphragm (see Figure 6).
4. When replacing the cage (key 5), insert the set
screws (key 39) only far enough to retain the cage.
Do not tighten.

Carefully tuck the slack diaphragm
material into the space between the
diaphragm plate (key 21) and lower
casing (key 7) until the diaphragm
ts smoothly over the diaphragm
plate without wrinkles and the bead
ts snugly and evenly in the groove
provided in the lower casing. This can
be done with a small screw screwdriver,
but be careful not to puncture the
diaphragm (see Figure 6).

faces away from the orice.
11. Install the E-ring (key 26) on the stem sleeve
(key 25) and slide the stem sleeve over the stem
(key 18) aligning the slotted end of the stem sleeve
so that the roll pin (key 27) can be inserted through
the cross-drilled hole in the end of the stem.
CAUTION
Always use the stem sleeve wrench
ats when loosening or tightening the
nuts (key 20 or 31) to prevent twisting
of the main and balancing diaphragms
(keys 15 and 22).
