Figure 2. Type CS200IR Pressure Reducing Regulator with Internal Relief Operational Schematic
Principle of Operation
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
orice and reduces gas ow. 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 orice.
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-
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 orice’s seating surface, or debris has become lodged between the primary disk and primary orice,
the outlet pressure will continue to rise. This additional pressure causes the primary disk to apply additional force
to the orice 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.

Type CS206 Secondary Seat Protection with Bleed
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 orice
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

Build-up
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:
• 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
• 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 orice/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 ow 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
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.
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.
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 Specications 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 ow 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 trafc 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.

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. Check to see that all appliances are turned off.
2. Slowly open the upstream shutoff valve.
3. Check inlet and outlet pressure for correct values.
4. Check all connections for leaks.
5. 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 rst isolating the
regulator from system pressure and relieving all internal pressure as described in “Shutdown”.
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 orice 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
8
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 Orice
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 orice
(key 25, Figure 7) is nicked or rough, remove the
orice from the body using a 7/8-inch / 22 mm
socket wrench.
b. If equipped with a Type CS205/206
Secondary Seat™ orice 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 orice assembly from the body using a 7/8-inch / 22 mm socket wrench.
Apply anti-seize lubricant to the external threads of
the new orice and reassemble.
Note
If the orice 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 ttings and a
good quality lubricant be applied to all O-rings except
when replacing key 19, as key 19 is a friction t 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.
