Internal View of CS800 Series with High Capacity Relief Introduction The CS800 Series direct-operated, spring-loaded regulators have been engineered to fit a multitude of commercial and industrial pressure-reducing applications. This flexibility is provided by the numerous body sizes and end connections, outlet pressure settings, orifice sizes, as well as the option for internal or external pressure registration. In addition to application flexibility, the CS800 Series offers multiple overpressure protection options: Overpressure Protection Options Available • Internal Relief – Provides overpressure protection to the downstream system by relieving gas through the diaphragm assembly to atmosphere in the event of an overpressure situation. • High-Capacity Internal Relief – Provides an increase in relief performance over internal relief thereby offering a significant improvement in the level of overpressure protection to the downstream system in the event of an overpressure occurrence. 4 • True-Monitor™ Protection – Combines the operation of a conventional two-regulator wideopen monitor set into one body. Provides a second monitoring regulator to control downstream pressure. In event of loss of downstream pressure control by the primary regulator due to damage to the lever, downstream sense line, orifice, disk, diaphragm, etc., the monitoring regulator will assume control of the downstream pressure and regulator flow. • Secondary Seat™ Protection – Provides a solution to the most common cause of regulators failing to shut off by employing a secondary seating surface to provide shutoff in the event the primary orifice seating surface becomes damaged or blocked. See page 15 for additional information. • Slam-Shut Protection – Discontinues gas service by shutting the gas off if there is an overpressure or underpressure condition. Overpressure Relief • Token Relief – Provides overpressure relief via a small capacity or token relief that relieves minor overpressure caused by thermal expansion or minor nicks in the orifice or disk.

Principle of Operation and Overpressure Protection Types CS800, CS820 and CS850 Base Regulator Operation Refer to Figures 3 and 4. When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by the regulator 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, the valve disk moves away from the orifice and the gas flow increases downstream as the regulator opens in response to the decreased pressure underneath the diaphragm. Relief Operation Internal Relief “R” Type numbers with the “R” suffix, e.g., Type CS800IR, provide internal relief discharge through the diaphragm assembly (see Figure 3) to minimize overpressure. Any outlet pressure above 10 the start- to- discharge point of the non-adjustable relief spring (see Table 5) moves the diaphragm off the relief seat, allowing excess pressure to discharge through the vent. If 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. Since the diaphragm continues to rise as downstream pressure builds, the diaphragm lifts off of the relief seat to provide relief operation. This secondary travel stop for internal relief is not available on token relieving units. Units with internal relief valve have 1 NPT vent size. See Figures 9, 11, 13, 15, 17 and 19 for relief capacity. High-Capacity Internal Relief “Q” Type numbers with the “Q” suffix, e.g., Type CS800IQ, provide high capacity relief discharge across the diaphragm assembly to minimize overpressure. Any outlet pressure above the start-to-discharge point of the non-adjustable relief spring (see Table 5) moves the diaphragm off the relief seat, allowing excess pressure to discharge through the vent. 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 Bulletin 71.1:CS800 adjusting screw relief valve stem control spring relief valve spring DIAPHRAGM ASSEMBLY regulator orifice pusher post regulator disk VALVE STEM lever M1070 INLET PRESSURE OUTLET PRESSURE ATMOSPHERIC PRESSURE Figure 3.

Maximum Discharge Capacity for Token and Low Flow Token Relief travel of the relief seat. Since the diaphragm continues to rise as downstream pressure builds, the diaphragm lifts off of the relief seat to provide relief operation. The secondary travel stop for internal relief is not available on token relieving units. Units with high capacity internal relief valve have 2-1/2 NPT vent size. See Figures 10, 12, 14, 16, 18 and 20 for relief capacity. Token Relief “T” and Low Flow Token Relief “L” Type numbers with the “T” or “L” suffix, e.g., Types CS800IT and CS800IL provide a low capacity/ token relief. Token relief provides relief from minor overpressure caused by nicks or dents on the orifice or by thermal expansion of gas in the downstream line. Token relief also provides a token or signal, in the form of odor, that an overpressure situation is occurring. Start-to-discharge values for Token reliefs are found in Table 5. Maximum discharge capacities for Token reliefs are found in Figure 8. Types CS803 and CS823 Integral True-Monitor™ Operation Types CS803 and CS823 combine the operation of a conventional two-regulator wide-open monitor set into one body, see Figure 5. The Integral True-Monitor is installed on the inlet side of the body and serves to control downstream pressure in the situation where the Primary regulator can no longer regulate downstream pressure. During normal operation the True-Monitor is in a wide-open state as its setpoint is set higher than the primary regulator. See Tables 7 and 8 for guidance regarding the setpoints of the regulator and associated Integral Monitor sets. If the downstream pressure should rise to the setpoint of the True-Monitor due to loss of pressure control by the primary regulator, the 14 monitor will assume control and regulate flow to the downstream system. Internal and external downstream pressure registration are available. External pressure registration requires a downstream sensing line. See the Type TM600 Instruction Manual for additional details of operation. If a Token relief is present, the token relief will relieve a small amount of gas to the atmosphere as an indication that the Integral Monitor is controlling the downstream pressure. Types CS804, CS824 and CS854 Slam-Shut Operation The Type VSX8 Slam-shut module on the CS804 Series regulators is a fast acting shutoff device that provides overpressure (OPSO) or overpressure and underpressure (OPSO/UPSO) protection by completely shutting off the flow of gas to the downstream system. See Tables 12 and 13 for guidance regarding the typical setpoint of the regulator and associated OPSO and UPSO sets. The Type VSX8’s actions are independent of the CS804 Series regulator and of variations to the inlet pressure. The Type VSX8 provides the option of internal or external downstream pressure registration. External registration requires a downstream sensing line. The Type VSX8 shutoff disk is normally in the open (reset) position, see Figure 6. If the downstream pressure below the slam-shut diaphragm increases (or decreases) until it reaches the slam-shut setpoint, this diaphragm moves upward (or downward) to release the trip mechanism which allows the spring force on the stem to push the disk against the seat, shutting off all gas flow. To reset the slam-shut after gas has been shutoff, refer to Type VSX8 Instruction Manual (D103127X012) for additional details. Bulletin 71.1:CS800 Note In order for the Underpressure Shutoff (UPSO) of any slam-shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint. These factors include the distance of pipe to the break, the diameter of the pipe, size of the break and the number of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be installed to stop flow in the event of a line break. Types CS805 and CS825 with Secondary Seat™ Protection Note Types CS805 and CS825 regulators do not have any means to alert when the Secondary Seat operates at lockup. Therefore, it is recommended that Internal relief or high-capacity relief are 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. Refer to Figure 7. The Type CS805 provides Secondary Seat Protection. As downstream demand decreases and downstream pressure rises to the regulator pressure lockup value, the regulator will lockup. If, however, damage has occurred to the primary disk, to the primary orifice 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. See Table 6 for Secondary Seat shutoff above setpoint. Types CS806 and CS826 Secondary Seat Protection with Bleed The Types CS806 and CS826 provides small bleed to the downstream system as an indication that the Secondary Seat is providing lock-up. 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, combined with a small drilled bleed hole, 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 6 for Secondary Seat maximum downstream buildup. Secondary Seat Protection Limitations Note Overpresssure 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. Installation The CS800 Series regulators may be installed in any position. However, the spring case vent should be pointed downward. If gas escaping through the CS800 Series internal relief valve could constitute a hazard, the spring case vent must be piped to a location where escaping gas will not be hazardous. If the vented gas will be piped to another location, use obstruction-free tubing or piping at least equal in size to the vent; protect the end of the vent pipe from anything that might clog it. Regulators with External Registration require the use of an external control line. 15 Bulletin 71.1:CS800 Non-Relieving “N” Type numbers with the “N” suffix, e.g., Type CS800IN, do not provide internal relief discharge through the diaphragm assembly. The CS800 Series regulators have outlet pressure ratings that are lower than their inlet pressure ratings. A pressure relieving or pressure limiting device is needed if the application inlet pressure can exceed the outlet pressure rating and the regulator is not equipped with internal relief, high capacity relief, Integral True-Monitor™ Protection or Secondary Seat™ Protection. Note Overpressuring any portion of a regulator or associated equipment may cause personal injury, leakage or property damage due to bursting of pressure-containing parts or explosion of accumulated gas. Provide appropriate pressure relieving or pressure limiting devices to ensure that the limits in the specifications section are not exceeded. Regulator operation within ratings does not prevent the possibility of damage from external sources or from debris in the pipeline. nitrogen, multiply the capacity number in the tables by the following appropriate conversion factor: 0.775 for air, 0.628 for propane, 0.548 for butane or 0.789 for nitrogen. For gases of other specific gravities, multiply the given capacity by 0.775 and divide by the square root of the appropriate specific gravity. Relief Sizing For critical flow: To determine wide-open flow capacities for relief sizing of 0.6 specific gravity natural gas at 60°F at critical pressure drops (absolute outlet pressure equal to approximately one-half or less than one-half of the absolute inlet pressure), use the following formula: Q=P1abs(Cg)(1.29) For subcritical flow: If pressure drops are lower than critical (absolute outlet pressure greater than approximately one-half the absolute inlet pressure), use the following formula and convert according to the factors in the preceding paragraph if necessary: Q= 520 GT CgP1SIN 3417 ∆P C1 P1 DEG Downstream Control Line Connection A CS800 Series regulator with an EN, ET or ER in the type number has a blocked throat, an O-ring stem seal and a 3/4 NPT control line tapping in the lower diaphragm casing, see Figure 4. A regulator with a downstream control line is used for monitoring installations or other applications where there is other equipment installed between the regulator and the pressure control point. The O-ring stem seal helps separate body pressure from diaphragm case pressure on monitor installations where leakage cannot be tolerated. Capacity Information Tables 14 through 66 provide natural gas regulating capacities at selected inlet pressures, outlet pressure settings and body outlet sizes. Flows are in scfh (60°F and 14.7 psia) and Nm3/h (0°C and 1.01325 bar) of 0.6 specific gravity natural gas.
