General Information Outlet pressures between.5" W.. and PSIG are available. Operating temperature range is -0 F to 50 F (-0 to 65 ). Maximum flow rate is 500 SFH (70.8 m /h). ll models conform to NSI ode , and G Service-Type Regulator Specification N/G-6.8-M95. Features Variety of interchangeable orifices and spring ranges 90 egree (Right ngle), 80 egree (Straight-Flow), or Offset Valve ody (See photo on next page) Wide range of valve body connection sizes Options Vent lbow The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a /" NPT plastic, 90 vent elbow (part number 780P05) and separate protective screen (part number 7000P07) may be screwed into the vent to provide the necessary protection. levation ompensation The.. orifice is recommended for installations where the inlet pressure may vary over a wide range. The.. orifice is available in two sizes: /8" x /6" and /6". The capacities of these orifices are the same as the standard orifice of the same size. pplications Model Number H Full apacity Relief Valve Full capacity relief valve standard on some models.

Safety Shutoff evices Overpressure Shutoff (OPSO) Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. These are available in two pressure ranges on the Models 8, 8-H, 8-L, 85, 88, 88-H, and 89. Spring Range Part Number " W.. to 5" W.. 70P005 PSIG to / PSIG 70P00

3 800 and 800-H Series Service Regulators 0 lster merican Meter When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm plate () compresses the pressure spring () forcing the diaphragm stem () upwards and releasing plunger (). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double-ended orifice. OPSO iaphragm Plate Pressure Spring ap Plunger iaphragm Stem F Shut-off Spring G Shut-off isc H djusting Screw Underpressure Shutoff (UPSO) The 8, 8, 85, and the 89 regulators come equipped with an underpressure shutoff (UPSO) device which utilizes a spring loaded valve stem and o-ring assembly within an orifice body. It will shut off gas flow through the regulator in the event of an upstream underpressure condition. UPSO in the Open position Under normal operating conditions, gas flows through the orifice from the high pressure upstream to the low pressure downstream. If conditions should change to cause the upstream pressure to decrease, the plunger and seat disk assembly will move away from the orifice thereby opening up the regulator to compensate for the lower inlet pressure. The spring in the Underpressure Shutoff will push the valve stem assembly up against the face of the seat disk. ventually the valve stem s o-ring will make contact with the inner wall of the orifice and completely shut off the gas flow. H F G UPSO in the losed position When the inlet underpressure condition has been corrected or repaired, the UPSO must be manually reset to allow gas flow. Reset is done by unscrewing the seal plug and pulling up on the diaphragm stem. This will open the Underpressure Shutoff and allow gas to flow. Seal Plug This type of design allows service maintenance to be performed to downstream appliances before pressure is introduced, i.e. lighting the pilot light, closing valves, etc. In some cases downstream failure may result in the regulator shutting off. xcessive flow may result in a decrease in downstream pressure which opens the seat disk away from the orifice until the Underpressure Shutoff takes over and shuts the regulator off. The design has been tested and meets capacity requirements, while insuring efficient and reliable resetting operation even at sub-zero temperatures. apacities of the Underpressure Shutoff orifice: iaphragm Stem Set Point: 7 W..

Q P P h G Maximum capacity of regulator constant (see table below) absolute pressure (PSI) Outlet absolute pressure (PSI) ifferential pressure Specific gravity of gas onstants /8" 5 /8" x /6" 5 /6" 57 /" 98 5/6" 9 /8" 08 /" 5 9/6" Maximum Recommended Pressure Size Pressure (PSIG) 9/6" 0 /" 0 /8" 00 5/6" 0 /" 5 /6" 5 /8" x /6" 5 /8" 5 This is the maximum inlet the regulator should operate at to insure complete lockup at no-flow conditions. Other Gas apacities To determine the capacity of these regulators for gases other than natural gas, multiply the values within the capacity tables by a Specific Gravity onversion Factor (F g). The table below lists this factor for some of the more common gases. Gas Type Specific Gravity onversion Factor (F g ) ir utane arbon ioxide Nitrogen Propane To calculate the onversion Factor for other gases: (F g) = Specific gravity of gas on which the capacity table is based Specific gravity of gas being used xample: If using propane and only having tables based on natural gas, the Specific Gravity onversion Factor is: (F g) = (F g) = (F g) = 0.66 Specific gravity of natural gas (0.6) Specific gravity of propane (.5) Regulator Pressure Rating 5 PSIG (8.6 bar) = Maximum recommended inlet pressure for normal service. Maximum recommended pressure may vary with orifice size. 75 PSIG ( bar) = Maximum inlet pressure for abnormal or emergency service, without causing damage to regulator case. PSIG (8 mbar) = Maximum outlet pressure for normal service. 0 PSIG (689 mbar) = Maximum outlet pressure which can be contained by pressure carrying components (no flange leakage to atmosphere except for normal relief action). If regulator is subjected to these conditions, it should be removed from service. 50 PSIG (.5 bar) = Maximum outlet pressure for abnormal service without damage to internal components. If regulator is subjected to these conditions, it should be removed from service.

11 800 and 800-H Series Service Regulators lster merican Meter 8-L Regulator with Limited Relief The 8-L has a limited relief feature that reduces the amount of gas released to the atmosphere. General Information Limited Relief is accomplished by installing a relief restriction cup inside the diaphragm assembly of the 8 regulator. The 8-L regulator utilizes overpressure protection as part of its assembly, which will shut off the gas in the event of over pressure condition.

18 800P Service Regulators General Information The merican Meter Series 800P pressure regulator is designed for natural gas applications and features a compact, lightweight design for fast, easy installation. The 800P regulator consists of a main regulator and a pilot regulator. It is a downstream bleed, pressure loaded regulator, designed to provide stability of operation for precise and constant outlet metering pressure control. The regulator is capable of handling varying inlet pressures up to 5 PSIG while controlling a set constant outlet pressure ( to 0 PSIG) within % of the absolute set pressure over a wide range of flow rates. The main regulator is normally closed, furnished with one spring (for all outlet pressures) to close the regulator if loading pressure fails. The pilot regulator outlet line mounts to the main regulator vent and connection tubing brings the main regulator inlet pressure to the pilot regulator inlet. The pilot regulator (one spring controls all outlet pressures from PSIG to 0 PSIG) is used to load pressure on the diaphragm of the main regulator. djustment of the pilot regulator depends upon the inlet pressure and outlet pressure range desired. The pilot regulator using upstream pressure as its supply, reduces this pressure to a predetermined value and then loads the main regulator diaphragm. The loading pressure overcomes the force of the main regulator spring causing the main regulator to open. pplication The 800P regulator is designed for pressure reducing service requiring stability and metering accuracy. They are used on gas distribution systems as intermediate or low pressure regulators. They are also effective for large farm and commercial operations with widely varying inlet pressures up to 5 PSIG with accurate control of outlet pressures between PSIG and 0 PSIG. 800P regulators are excellent for use with merican Meter large capacity meters as well as with merican Meter domestic meters. Model 88P is equipped with overpressure shut-off (OPSO) that provides protection against downstream overpressure (see page 6). The 800P regulator will accurately control the metering pressure to a constant value, thus the pressure correction factor becomes a constant factor for a given metering pressure. The pressure-corrected volume equals meter volume multiplied by the pressure factor constant. xclusive, 7 - Step orrosion Protection The protective finish on the Series 800P regulators resists corrosive effects of weather and harsh environments better than any other in the industry. ach precision die cast aluminum regulator is treated-inside and out-with a special conversion coating that's part of an exclusive, 7-step finishing process. This coating greatly inhibits oxidation of the metal's surface that can eventually compromise the integrity of the metal. It also prevents finish paint from cracking and blistering. single coat polyester primer and the high solid polyurethane top coat provides a long-lasting protection to all exterior regulator surfaces. The merican Meter conversion coating process meets all environmental protection regulations. High Tensile Strength Valve odies ach Series of 800P regulator is equipped with a high tensile strength cast iron valve body and features extra heavy wall thickness. This provides maximum strength to withstand installation stresses without damage and prevents thread galling experienced with aluminum. Series 800P regulator valve bodies are treated with a 5-step metal finishing process. The treated metal is primer painted with a single coat polyester paint. ➂ ➀ vailable valve body sizes are: /" x /", /" x ", /" x -/", " x ", " x -/" and -/" x -/" NPT or SP-TR. -60 luminumcase Meter ➁ 88P Regulator ➂ 800P Regulator ➀

19 800P Service Regulators Fixed Factor Measurement Fixed factor measurement is the measurement of gas at a controlled elevated pressure without the use of an automatic correcting device to correct the volume for variations from base or contract pressure. The 800P regulator provides accurately controlled, constant metering pressure for this application. Volume of gas being metered at other than base pressure, must be corrected to base or contract conditions. The merican Gas ssociation specifies that a cubic foot of gas at base conditions be defined as the quantity which occupies a volume of one cubic foot at a pressure of.7 PSI and at a temperature of 60 F. Therefore to determine the volume of gas at medium or high pressure, the volume must be corrected to base or contract pressure. The correction factor to correct volume for pressure is determined from oyle s Law: Volume orrected = Volume Metered x Metering Pressure + tmospheric Pressure ase Pressure Where temperature varies, merican Meter recommends the 800P regulator be used with a pressure compensating index for the desired metering pressure and with an merican Meter temperature compensated meter to provide accurate flow measurement without subsequent calculations. /" 9 /8" /" 7 /" 7 /" 8 7/8" 8 7/8" 8 /8" 8 /8" /" 9 /8" 9 /8" /8" 800P Regulator 88P Regulator

22 Overpressure Shut-off Regulators Overpressure Shut-off (OPSO) Regulators Model 88P regulators are compact units designed to regulate line pressure and to provide protection against any downstream overpressure. Rugged, ompact OPSO - Operates independently. The OPSO will shut-off the gas supply in the event of a serious downstream pressure build-up. djustable Overpressure Shut-off - Pressure is adjustable via the overpressure shut-off adjustment screw to settings from 5 to 5 PSIG and 5 to 0 PSIG depending on spring selected. How The OPSO Operates When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm () compresses the pressure spring () forcing the diaphragm stem () upwards and releasing plunger (). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double ended orifice.

29 merican Meter UPSO OPSO OUPSO Regulator Safety Features vailable xclusively From merican Meter On Series 800 and 000 Industrial Regulators Pressure control and automatic shutoff devices for the protection of public buildings, schools, theaters, hospitals, etc. are available in one complete package on several 800 and 000 Series Industrial Regulator models (see page 5). Installing one of these regulators provides automatic protection against possible extreme variations in either inlet or outlet gas pressure. UPSO The UPSO (underpressure shutoff) models provide complete shutoff protection in case of severely interrupted inlet gas pressure. If the inlet or outlet pressure is severely interrupted, causing the regulator to stroke to a full-open position, the shutoff closes, providing complete system safety. The shutoff valve remains closed until manually reset. How The UPSO Operates When gas pressure under the main diaphragm falls below normal, the shutoff device is tripped and the spring, connected with the valve plunger, forces the valve seat against the orifice closing off gas flow. The UPSO must be manually reset to re-establish gas flow. Figure To reset the underpressure shutoff device (Figure ), unscrew the reset plug with a wrench. When it becomes free of the threads, pull it out until it engages the reset mechanism. With the wrench, turn the reset shaft clockwise until the reset mechanism is engaged. Hold firmly in this position until normal pressure is established under the diaphragm and downstream line, and regulator operation is restored. Screw in the reset plug and tighten. Overpressure Shutoff (OPSO) in cocked position Overpressure Shutoff (OPSO) in tripped position OPSO Overpressure shutoff regulator models prevent excessive gas pressure from entering a building causing a hazardous condition. The shutoff device closes if the regulator outlet pressure rises above a maximum set point or set pressure. How The OPSO Operates When line or static pressure increases to the specified overpressure shutoff setting, the pressure on the under side of the shutoff diaphragm over-balances the spring, forcing the diaphragm stem outward, releasing the plunger. This permits the shutoff spring to force the shutoff disc against the orifice, closing off gas flow. The OPSO assembly is part of the regulator but is not connected to the regulator operating mechanism. When selecting a shutoff spring, a minimum differential of " w.c. between normal operating pressures and the shutoff pressure setting should be provided. To reset the overpressure shutoff device, unscrew the seal cap, which opens the regulator orifice, permitting gas flow. Pull out on the seal cap until the overpressure shutoff device latches completely. Tighten the seal cap. o not trip the shutoff valve unless the seal cap is installed. OUPSO Overpressure and underpressure shutoff models combine both safety features for maximum protection. On these models, when the OPSO shuts off, the UPSO automatically trips, providing double assurance of positive gas shutoff. The overpressure shutoff device must be reset first followed by resetting the underpressure shutoff device. 5

38 800 Service Regulators General Information The merican Meter Series 800 pressure regulators are designed for natural gas applications and features a compact, lightweight design for fast, easy installation. Interchangeable orifices and springs provide a wide range of outlet pressures and flow rates. Outlet pressures between.5" W.. and PSIG are available. Operating temperature range is -0 F to 50 F (-0 to 65 ). Maximum flow rate is 500 SFH (70.8 m/h). The diaphragm case may be easily removed for routine inspection without disturbing the line connections. ll models conform to NSI ode , and G Service-type Regulator Specification N/G-6.8-M95. xclusive, 7 - Step orrosion Protection The protective finish on the Series 800 regulators resists corrosive effects of weather and harsh environments better than any other in the industry. ach precision die cast aluminum regulator is treated-inside and out-with a special conversion coating that's part of an exclusive, 7- step finishing process. This coating greatly inhibits oxidation of the metal's surface that can eventually compromise the integrity of the metal. It also prevents finish paint from cracking and blistering. single coat polyester primer and the high solid polyurethane top coat provides a long-lasting protection to all exterior regulator surfaces. The merican Meter conversion coating process meets all environmental protection regulations. High Tensile Strength Valve odies ach Series of 800 regulator is equipped with a high tensile strength cast iron valve body that rotates in 90- degree increments and features extra heavy wall thickness. This provides maximum strength to withstand installation stresses without damage and prevents thread galling experienced with aluminum. overpressure. Valve body configuration permits the 800 Series regulators to be supplied in four positions as specified on page 9. ll Series 800 regulators are available with either right angle (90 degree) or straight flow (80- degree) valve bodies. Vents can also be supplied in four different positions. ll models are designed with an extra large, removable weather and bug-proof stainless steel screened vent to resist freeze-ups and to exclude foreign matter. The vent is threaded / or inch NPT and is also available with SP-TR threads making it suitable for indoor installations. Options Vent lbow- The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not, a /" NPT plastic, 90 vent elbow (Part number 780P05) and separate protective screen (Part number 7000P07) may be screwed into the vent to provide the necessary protection. levation ompensation-.. orifices are also available, which provide constant outlet pressure even when inlet pressure fluctuates greatly. The elevation compensation orifice is a device which reduces changes in regulator outlet pressure due to change in inlet pressure. The.. orifice is recommended for installations where the inlet pressure may vary over a wide range. The.. orifice is available in two sizes: /8" x /6" (Part number 7698G006) and /6" (Part number 7698G005). Its capacity is the same as a standard orifice of the same size. onsult your merican Meter Sales Representative for specific applications. ➁ Series 800 regulator valve bodies are treated with a 5- step metal finishing process.

39 800-H Service Regulators 8-H 8-H General Information Ideal for light commercial and industrial use, the -/" 800-H Series regulator is designed to increase output capacity and lessen compounding during mediumto high-inlet pressure operations. ompounding usually occurs when a larger valve body introduces undesirable flow characteristics, thereby creating an inefficient, boosting effect in the outlet port of the body. The 800-H regulator s lightweight design features high-capacity capabilities for -/" NPT connections and flow capacities up to 900 SFH depending on inlet pressure and orifice selection. It complements the 800 Series family of regulators. lightweight regulator designed to increase capacity output and minimize the outlet boosting effect that is typical from a larger valve body. ll models conform to NSI ode and G Service-type Regulator Specification N/G-6.8-M95. 8-H-80 imensions 7-/" -/8" " -/6" 8-5/6" 8-H imensions 7-/" -5/8" -5/8" /8" ➁ " -/" 8-5/6" ➀ -60 Meter ➁ 8-H Regulator

41 Overpressure Shut-off Regulator Overpressure Shut-off (OPSO) Regulators Models 8 and 8-H regulators are compact units designed to regulate line pressure and to provide protection against any downstream overpressure. Rugged, ompact OPSO - Operates independently. The OPSO will shut-off the gas supply in the event of a serious downstream pressure build-up. djustable Overpressure Shut-off - Pressure is adjustable via the overpressure shut-off adjustment screw to settings from " to 5" W.. and to -/ PSIG depending on spring selected. xtra Safety - Models 8 and 8-H provides added protection by incorporating a full capacity relief valve. This internal valve is the same as in the 8 and 8-H and operates in the same manner to combine safety features. How The OPSO Operates When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm () compresses the pressure spring () forcing the diaphragm stem () upwards and releasing plunger (). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double ended orifice. Overpressure Shut-off Tripped Position Shut-off ssembly 7978G G07 djustable Trip Point Range " to 5" W.. to -/ PSIG Note: When selecting the shut-off spring range, a differential of " W.. above the normal operating pressure and the shut-off pressure is recommended for normal line pressure variations. The OPSO setting is preset at the factory to the desired trip point. To reset the OPSO simply unscrew cap (), pull back the plunger () until the diaphragm stem () repositions.
