Principle
of Operation
ATMOSPHERIC PRESSURE
Type CS200 Base Regulator Operation
Refer to Figure 2. When downstream demand decreases,
the pressure under the diaphragm increases. This pressure
overcomes the regulator setting (which is set by the control
spring). Through the action of the pusher post assembly,
lever, and valve stem, the valve disk moves closer to the
orifice and reduces gas flow. If demand downstream
increases, pressure under the diaphragm decreases.
Spring force pushes the pusher post assembly downward
and the valve disk moves away from the orifice.
CS200 Series with Internal Relief
Refer to Figure 2. The option for Internal Relief is offered
on the Types CS200 and CS205 and is standard on the
Type CS206. Internal relief is used to help minimize
overpressure. Any outlet pressure above the start-todischarge point of the non-adjustable relief spring moves the
diaphragm off of the relief seat, allowing excess pressure
to discharge through the vent. Typical start-to-discharge
values are 7 inches w.c. to 1.5 psi / 17 to 103 mbar above
the outlet pressure setting, depending on control spring and
if the Secondary Seat™ option is present. Refer to Table 5
for Type CS205 lockup values and Type CS206 downstream
build-up values. Refer to the CS200 Series Bulletin for
additional information regarding Internal Relief start-to-
4
discharge both with and without Secondary Seat Protection.
If emergency conditions should exist that prevent normal
operation of the regulator or internal relief valve, the relief
valve stem acts as a secondary travel stop contacting the
underside of the closing cap and stopping the upward travel
of the relief seat. When the diaphragm continues to rise as
downstream pressure builds, the diaphragm lifts off of the
relief seat to provide relief operation.
Type CS205 with Secondary
Seat Protection
Refer to Figure 3. The Type CS205 provides
Secondary Seat Protection. As downstream demand
decreases and downstream pressure rises to the regulator
pressure lockup value, the regulator will lock up. If,
however, damage has occurred to the primary disk, to the
primary orifice’s seating surface, or debris has become
lodged between the primary disk and primary orifice,
the outlet pressure will continue to rise. This additional
pressure causes the primary disk to apply additional force
to the orifice seating surface, which causes the Secondary
seating surface to move toward the Secondary disk or
sealing surface. If downstream demand decreases to
zero, then the secondary seating surface will contact
the sealing surface to provide lockup. Refer to
Table 5 for approximate lockup values provided by the
Secondary Seat.

Secondary Seat Assembly.
The Type CS206 provides small bleed to the downstream
system as an indication that the Secondary Seat is
providing lockup. In the event that the primary orifice
and disk cannot provide lockup, the secondary seating
surface will move into contact with a metal disk. This
metal to metal interface will allow a small amount of gas
to bleed downstream thereby increasing outlet pressure
until the Internal relief valve begins to discharge gas
to the atmosphere. The odor of this discharged gas
provides an indication that the regulator is relying on
the Secondary Seat for overpressure protection. See
Table 5 for the Downstream Pressure Build-up of the
Types CS205 and CS206 Secondary Seat
Protection Limitations
caution
Overpressure conditions can occur
in the downstream piping when the
Secondary Seat Protection is installed. The Secondary Seat Protection
serves only as a backup to the primary
seat for lockup. Refer to the sections on
Overpressure Protection and Maintenance.

Secondary Seat Protection does not provide additional
overpressure protection in the event the secondary seat
or disk is damaged by debris or contamination in the
pipeline, or from conditions that would cause the regulator
to go wide-open. When selecting Secondary Seat
Protection, it is recommended that:
outdoor installations, point the spring case
vent downward to allow condensate to
drain (see Figure 4). This minimizes the
possibility of freezing and of water or other
foreign materials entering the vent and
interfering with proper operation.
• Internal Relief is also selected, or the addition of
some other method of overpressure protection be
added in the downstream system as discussed in the
Overpressure Protection section; and
Under enclosed conditions or indoors,
escaping gas may accumulate and be an
explosion hazard. In these cases, the vent
should be piped away from the regulator to
the outdoors.
• A periodic downstream lock-up pressure test is done
to determine if the Secondary Seat Protection option
is serving as the primary seat for shutoff, thereby
indicating that the primary orifice/seat or the disk
are no longer providing shutoff. This determination
is made by checking if the regulator lock-up value is
elevated to or near the values indicated in Table 5,
under the heading Type CS205
Installation and
Overpressure Protection
!
Warning
Personal injury or system damage may
result if this regulator is installed, without
appropriate overpressure protection,
where service conditions could exceed the
limits given on the regulator nameplate.
Regulator installations should
be adequately protected from
physical damage.
All vents should be kept open to permit
free flow of gas to the atmosphere. Protect
openings against entrance of rain, snow,
insects, or any other foreign material
that may plug the vent or vent line. On
6
caution
The CS200 Series regulators have an
outlet pressure rating lower than their
inlet pressure rating. If actual inlet
pressure can exceed the outlet pressure
rating, outlet overpressure protection is
necessary. However, overpressuring any
portion of the regulators beyond the limits
in the Specifications section may cause
leakage, damage to regulator parts, or
personal injury due to bursting of pressurecontaining parts.
Some type of external overpressure
protection should be provided if inlet
pressure will be high enough to damage
downstream equipment. Common methods
of external overpressure protection include
relief valves, monitoring regulators, shutoff
devices, and series regulation.
If the regulator is exposed to an
overpressure condition, it should be
inspected for any damage that may
have occurred. Regulator operation
below these limits does not preclude
the possibility of damage from external
sources or from debris in the pipeline.
CS200 Series
General Installation Instructions
Before installing the regulator,
• Check for damage, which might have occurred
during shipment.
• Check for and remove any dirt or foreign material,
which may have accumulated in the regulator body.
• Blow out any debris, dirt or copper sulfate in copper
tubing and the pipeline.
• Apply pipe compound to the external threads of the
pipe before installing the regulator.
• Make sure gas flow through the regulator is in the
same direction as the arrow on the body. “Inlet” and
“Outlet” connections are clearly marked.

Installation Location
• The installed regulator should be adequately
protected from vehicular traffic and damage from
other external sources.
• Install the regulator with the vent pointed vertically
down, see Figure 4. If the vent cannot be installed
in a vertically down position, the regulator must be
installed under a separate protective cover. Installing
the regulator with the vent down allows condensation
to drain, minimizes the entry of water or other debris
from entering the vent, and minimizes vent blockage
from freezing precipitation.
• Do not install the regulator in a location where
there can be excessive water accumulation or ice
formation, such as directly beneath a downspout,
gutter, or roof line of building. Even a protective
hood may not provide adequate protection in
these instances.
• Install the Regulator so that any gas discharge through
the vent or vent assembly is over 3 feet / 0.91 m away
from any building opening.
Regulators Subjected to Heavy
Snow Conditions
Some installations, such as in areas with heavy snowfall,
may require a hood or enclosure to protect the regulator
from snow load and vent freeze over.
Installation with External
Overpressure Protection
If the regulator is used in conjunction with a Type 289H
relief valve, it should be installed as shown in Figure 4.
The outside end of the vent line should be protected with
a rainproof assembly.
The Type 289H is typically set 10-inches w.c. / 25 mbar
higher than the outlet pressure setting of the regulator, up
to 30 inches w.c. / 75 mbar outlet pressure. For pressure
greater than this, set the Type 289H 0.75 psi / 0.05 bar
higher than the outlet pressure setting of the regulator.
regulator vent
pointed downward
Figure 4. CS200 Series Regulator Installed with Vent Pointed
Downward and with a Type 289H Relief Valve
for High Capacity Relief
Vent Line Installation
The CS200 Series regulators have a 1 NPT screened
vent opening in the spring case. If necessary to vent
escaping gas away from the regulator, install a remote
vent line in the spring case tapping. Vent piping should
be as short and direct as possible with a minimum
number of bends and elbows. The remote vent line
should have the largest practical diameter. Vent piping
on regulators with internal relief must be large enough
to vent all relief valve discharge to atmosphere without
excessive backpressure and resulting excessive pressure
in the regulator.
Periodically check all vent openings to be sure that they
are not plugged or obstructed.
Outlet pressure ranges are shown on Table 3. Outlet
pressure greater than 5 psi / 0.34 bar above the setpoint
may damage internal parts such as the diaphragm head
and valve disk. The maximum emergency (casing)
outlet pressure is 25 psig / 1.7 bar.
Startup
caution
Pressure gauges must always be used
to monitor downstream pressure during
startup. Procedures used in putting this
regulator into operation must be planned
accordingly if the downstream system is
pressurized by another regulator or by a
manual bypass.
7
CS200 Series
If the downstream system is not pressurized by another
regulator or manual bypass valve, use the following
procedure to startup the regulator.
1.
2.
3.
4.
5.
Check to see that all appliances are turned off.
Slowly open the upstream shutoff valve.
Check inlet and outlet pressure for correct values.
Check all connections for leaks.
Turn on utilization equipment and recheck
the pressures.
Adjustment
Note
The range of allowable pressure setting is
stamped on the nameplate. If the required
setting is not within this range, substitute
the correct spring (as shown in Table 3). If
the spring is changed, change the nameplate
to indicate the new pressure range.
A pressure gauge must always be used to monitor
downstream pressure while adjustments are being made.
1. Remove the closing cap (key 60, Figure 5).
2. To increase the outlet setting, turn the adjusting screw
(key 65, Figure 5) clockwise. To decrease the outlet
setting, turn the adjusting screw counterclockwise.
3. Replace the closing cap.
Shutdown
Installation arrangements may vary, but in any
installation it is important that the valves be opened or
closed slowly and that the outlet pressure be vented
before venting inlet pressure to prevent damage caused
by reverse pressurization of the regulator. The steps
below apply to the typical installation as indicated.
1. Open valves downstream of the regulator.
2. Slowly close the upstream shutoff valve.
3. Inlet pressure should be automatically released
downstream as the regulator opens in response to the
lowered pressure on the diaphragm.
4. Close outlet shutoff valve.
Maintenance
!
Warning
To avoid personal injury or equipment
damage, do not attempt any maintenance
or disassembly without first isolating the
regulator from system pressure and relieving
all internal pressure as described
in “Shutdown”.
8
Regulators that have been disassembled for
repair must be tested for proper operation
before being returned to service. Only parts
manufactured by Regulator Technologies
should be used for repairing Fisher®
regulators. Restart gas utilization equipment
according to normal startup procedures.
Due to normal wear or damage that may
occur from external sources, this regulator
should be inspected and maintained
periodically. The frequency of inspection
and replacement of parts depends upon
the severity of service conditions or the
requirement of local, state, and federal
rules and regulations.
Maintenance on Types CS205 and CS206
Secondary Seat™ Protection
The Type CS205 regulator does not have any means
to alert when the Secondary Seat operates at lockup.
Therefore it is recommended that a periodic lockup
test be done on the regulator to determine if the lockup
pressure has elevated to the values in Table 5. If so, the
regulator primary disk and orifice should be replaced.
Types CS205IR and CS206IR have internal relief. Internal
relief operation on these units is an indication that the
Secondary Seat Protection on the Type CS205IR may not
be working and that the Type CS206 Secondary Seat may
have closed. Maintenance should address any potential
causes for internal relief operation as well as other
regulator malfunctions separate from the Secondary Seat.
Disassembly to Replace Diaphragm
1. Remove the closing cap (key 60, Figure 5). Turn the
adjusting screw (key 65) counterclockwise to ease
spring compression.
2. Remove the adjusting screw and spring (key 38).
3. Remove hex nuts (key 16) and cap screws (key 15).
Separate the upper spring case (key 1) from
the lower casing assembly (key 9). Note
vent orientation.
Note
When disassembling a CS200 Series
regulator, lift the upper spring case
straight up in order to avoid hitting the
relief valve stem (key 44, Figure 5).
4. Slide the diaphragm assembly (key 55) away from
the body (key 70) to unhook the pusher post (key 51)
from the lever (key 10). Lift off the diaphragm head
assembly (key 55).
5. For Types CS200IN and CS205IN (Non-relieving
units), unscrew the retainer screw (key 45, Figure 6)
using a 5/8-inch / 16 mm wrench. The screw retainer
CS200 Series
fastens the lower spring seat (key 43) to the pusher
post (key 51). Unscrewing the screw retainer will
separate the lower spring seat (key 43), diaphragm
and diaphragm assembly (key 55), and pusher post
(key 51).
For Type CS200IR, CS205IR, and CS206IR (units
with internal relief), press down on the upper spring
retainer (key 42, Figure 6) using a 9/16-inch / 14 mm
box-end wrench and remove the retaining ring (key 58).
Slide the upper spring retainer (key 42), the relief
spring (key 41), the lower spring seat (key 43) and the
diaphragm assembly (key 55) off of the relief valve stem
(key 44).
6. Reassemble regulator in the reverse order of the
above steps.
Disassembly to Replace Valve Disk
and Orifice
1. Remove the bolts (key 71, Figure 5) which hold the
lower spring casing (key 9) to the body (key 70).
Separate the lower spring casing from the body.
2. Check the body O-ring (key 21) for wear and replace
as necessary.
3. Examine the valve disk (key 36, Figure 5) for nicks,
cuts, and other damage. Remove the disk by pulling
and replace it with a new part if necessary.
4. a. If the seating edge of the Type CS200 orifice
(key 25, Figure 7) is nicked or rough, remove the
orifice from the body using a 7/8-inch / 22 mm
socket wrench.
b. If equipped with a Type CS205/206
Secondary Seat™ orifice assembly, inspect the
primary seating surface as well as the secondary
seating surface and sealing surface. If nicks or other
damage are present, remove the orifice
assembly from the body using a 7/8-inch / 22 mm
socket wrench.
Apply anti-seize lubricant to the external threads of
the new orifice and reassemble.
Note
If the orifice is being replaced with a
different size, change the nameplate
to state the new size and maximum
inlet pressure. 5. Reassemble the regulator in reverse order of the
above steps.
Regulator Reassembly
It is recommended that a good quality pipe thread sealant
be applied to pressure connections and fittings and a
good quality lubricant be applied to all O-rings except
when replacing key 19, as key 19 is a friction fit O-ring for
holding the stem guide into the lower casing. Also apply
an anti-seize compound to the adjusting screw threads
and other areas as needed. Refer to Figures 5 through 7.
Parts Ordering
