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
efciency 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 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
orice 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).

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 pressures
higher than the inlet pressure, or the

Also, the control line pressure must never

exceed the set point dictated by the spring

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. Slowly open the upstream shutoff valve.

2. Slowly open the downstream shutoff valve.

3. Check all connections for leaks.

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), 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 (key 38), 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.

Maintenance

WARNING

!

To avoid personal injury, property
damage, or equipment damage
caused by sudden release of pressure

or explosion of accumulated gas,

do not attempt any maintenance or

disassembly without rst isolating the

regulator from system pressure relieving
all internal pressure from the equipment.

Do not loosen the diaphragm casing
cap screws (keys 35 and 36) when
the control spring (key 12) has spring
force applied to it. Release the spring
compression as described in step 6.

Disassembly

1. Disconnect the downstream control line from the

regulator and disconnect the remote vent pipe if
one is used.

Note

Allowing a slight amount of compression
to remain in the regulator spring will
facilitate disassembly of the trim parts.

2. Unscrew the four nuts (key 34) and lift the actuator
portion off the body (key 1). All of the trim parts
will come out of the body with the actuator. The
valve disk (key 28), orice (key 2), and restriction
collar (key 46, Figure 13), if used, can be inspected.

Due to normal wear that may occur in gas regulators,
parts must be periodically inspected and replaced

if necessary. The frequency of inspection depends
on the severity of service conditions or state and

federal laws. This section includes instructions
for disassembly and replacement of parts. All key
numbers refer to Figures 10, 11, 12, 14, and 15 except
where indicated.

8. Unscrew the cap screws and nuts (keys 35 and 36)

and remove the spring case.

9. Pull out the diaphragm and stem as assembly;
replace diaphragm and sealing washer (key 17)

if necessary. When removing or replacing the

diaphragm, clamp the smallest diameter portion if
the stem in a vise while turning the nut (key 20).

10. If necessary, replace the guide bushing (key 6)

and the upper stem seal O-ring (see Figure 5).
Before reassembling, coat the O-ring with

Bell-ray No. 80 or an equivalent O-ring sealant

and lubricant.

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
and to facilitate reassembly of the trim parts,
tighten the casing cap screws nger-tight only.
Then adjust the spring 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 Dow Corning No. 3 or an equivalent
elastomer sealant and lubricant.

3. When installing the balancing diaphragm, 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

133 Series

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 no to puncture the
diaphragm (see Figure 6).

4. When replacing the cage, insert the set screws
(key 39) only far enough to retain the cage.

Do not tighten.

5. The registration disk (key 29) is marked for
proper placement; be certain it is positioned

correctly on 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).

6. Be certain the Belleville spring washer (key 3) is
in good condition and is in place before placing
the actuator on the body.

2. Unscrew the four locknuts (key 34) and lift the
actuator portion off the body (key 1). All of the trim
parts will come out of the body with the actuator.
The valve disc (key 28), orice (key 2), and
restriction collar (key 46) can now be inspected.

CAUTION

Use care in performing step 3 to guard
against damage to the balancing
diaphragm (key 22).

3. Insert a 1/2-inch (12,70 mm) open-end wrench
between the legs of the cage (key 5) and place
the wrench on the stem sleeve wrench ats. Hold
this wrench while unscrewing the nut (key 31) to
prevent stem and stem sleeve (keys 18 and 25)
rotation and diaphragm damage due to twisting.

4. Remove the washer, registration disc and
valve disc (keys 30, 29, and 28). To remove the
restriction collar loosen the set screw (key 47) and
slip the E-ring (key 26) and collar off the stem. Lift
off the orice (key 2) and replace the valve disc
and orice if necessary.

6. Assemble the upper and lower casings, noting
that two of the holes in the 5-1/4-inch (133 mm)
diameter bolt circle in the mounting plate adaptor
must be spaced (aligned) an equal distance over
the downstream control line connection. Install
cap screws and hex nuts (keys 35 and 36) with a

torque of 20 to 30 foot-pounds.

7. Place the balancing plate washer (Figure 15,
key 23), balancing diaphragm plate (key 21),
balancing diaphragm (key 22) and a second
balancing plate washer (key 23), onto the stem
(key 18).

Note

When installing the balancing
diaphragm, 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 and lower casing
(Figure 6, 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.

Install the Belleville spring washer (key 3) so that
the concave face of the washer faces away from
the orice.

11. Install the E-ring (key 26) on the stem sleeve

(key 25) and slide the stem sleeve over the stem

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 (keys 20 or 31) to prevent twisting
of the main and balancing diaphragms
(keys 15 and 22).
