SB-855.8 800 & 800-H Service Regulators Maximum Pressure 5 PSIG
800 Regulator Information 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 B09.-998, 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 Bodies 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 BSP-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. The treated metal is painted with a single coat polyester paint. vailable valve body sizes are: /" x /", /" x ", /" x -/", " x ", " x -/" and -/" x -/" NPT or BSP-TR. lso available is a offset valve body in /" x /", /" x " and " x " NPT or BSP-TR. pplication Models 8 and 8 features a full capacity internal relief valve with large passages to assure the fast release of gas (See performance graphs on page 6). For added protection, a relief valve stop is provided to assure operation under the most severe conditions. The standard relief spring setting is 8.0" W.. above the normal 7" W.. outlet pressure. -50 Meter ➁ 8 Regulator ➀ Models 8 are equipped with overpressure shut-off (OPSO) that provide protection against downstream
800-H Regulator Information 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 B09.-998 and G Service-type Regulator Specification N/G-6.8-M95. 8-H-80 Dimensions 7-/" -/8" " -/6" 8-5/6" 8-H Dimensions 7-/" -5/8" -5/8" /8" ➁ " -/" 8-5/6" ➀ -60 Meter ➁ 8-H Regulator

Overpressure Shut-off Regulators 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 (B) forcing the diaphragm stem () upwards and releasing plunger (D). 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 B Shut-off ssembly 7978G070 7978G07 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 (D) until the diaphragm stem () repositions.
