800C Regulator Information General Information The American Meter Series 800C pressure regulators are designed for natural gas applications and feature 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.C. and are available. Operating temperature range is -0 F to 50 F (-0 C to 65 C). Maximum flow rate is 500 SCFH (70.8 m /h). The diaphragm case may be easily removed for routine inspection without disturbing the line connections. All models conform to ANSI Code B09.-998, and CGA Service-Type Regulator Specification CAN/CGA-6.8-M95. Exclusive Seven- Step Corrosion Protection The protective finish on the Series 800C regulators resists corrosive effects of weather and harsh environments better than any other in the industry. Each precision die-cast aluminum regulator is treated inside and out with a special conversion coating that is part of an exclusive, seven-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. A single-coat polyester primer and the high solid polyurethane top coat provide long-lasting protection to all exterior regulator surfaces. The American Meter conversion coating process meets all environmental protection regulations. High Tensile Strength Valve Bodies Each series of 800C regulator is equipped with a high tensile strength cast-iron valve body that rotates in 90 increments and features extra-heavy wall thickness. This provides maximum strength to withstand installation stresses without damage and prevents thread galling experienced with aluminum. Series 800C regulator valve bodies are treated with a five-step metal-finishing process. The treated metal is painted with a single-coat polyester paint. The standard relief spring setting is 8" W.C. above the normal 7" W.C. outlet pressure. Model 8C is equipped with overpressure shut-off (OPSO) that provides protection against downstream overpressure. Valve body configuration permits the 800C Series regulators to be supplied in four positions as specified on page 0. All Series 800C regulators are available with either right-angle (90 ) or straight-flow (80 ) valve bodies. Vents can also be supplied in four different positions. All models are designed with an extra-large, removable weather-proof and bug-proof stainless-steel screened vent to resist freeze-ups and to exclude foreign matter. The vent is threaded /" or " NPT and is also available with BSP-TR threads making it suitable for inside installations. Inside installation requires a vent line of sufficient diameter to carry gas vented by the regulator to a safe outside location away from any opening in the building. Options Vent Elbow 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. Elevation Compensation E.C. 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 E.C. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.C. 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. Consult your American Meter sales representative for specific applications. Available valve body sizes are: /" x /", /" x ", /" x -/", " x ", " x -/" and -/" x -/" NPT or BSP-TR. Also available is an offset valve body in /" x /", /" x " and " x " NPT or BSP-TR. Application Models 8C and 8C feature full-capacity internal relief valves with large passages to assure the fast release of gas (see performance graphs on page 9). For added protection, a relief valve stop is provided to assure operation under the most severe conditions. AC-50 Meter with 8C Regulator
800C-HC Regulator Information General Information Ideal for light commercial and industrial use, the -/" 800C-HC Series regulator is designed to increase output capacity and lessen compounding during medium to high inlet pressure operations. Compounding 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 800C-HC regulator s lightweight design features high-capacity capabilities for -/" NPT connections and flow capacities up to 900 SCFH depending on inlet pressure and orifice selection. It complements the 800C Series family of regulators. All models conform to ANSI Code B09.-998 and CGA Service-Type Regulator Specification CAN/CGA-6.8-M95.

Overpressure Shut-Off Regulators General Information Models 8C and 8C-HC regulators are compact units designed to regulate line pressure and to provide protection against any downstream overpressure. Rugged, Compact OPSO Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. Adjustable Overpressure Shut-Off Pressure is adjustable via the overpressure shut-off adjustment screw to settings from " to 5" W.C. and to -/ depending on spring selected. Extra Safety Models 8C and 8C-HC provide added protection by incorporating a full-capacity relief valve. This internal valve is the same as in the 8C and 8C-HC and operates in the same manner to combine safety features. Overpressure Shut-Off Tripped Position How the OPSO Operates When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm (A) compresses the pressure spring (B) forcing the diaphragm stem (E) 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. Shut-off Assembly 7978G070 7978G07 Adjustable Trip Point Range " to 5" W.C. to -/ Note: When selecting the shut-off spring range, a differential of " W.C. 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 (C) and pull back the plunger (D) until the diaphragm stem (E) repositions. 800C and 800C-HC Service Regulators Full-Open Regulator Relief Capacity For sizing downstream relief valves, use the following formulas to determine the regulator full-open capacity: For critical flow rates For sub-critical flows Key Q = Maximum capacity of regulator C = Orifice constant (see table below) P = absolute pressure (PSIA) P = Outlet absolute pressure (PSIA) h = Differential pressure (P-P) G = Specific gravity of gas Orifice C /8" 5 /8" x /6" 5 /6" 57 /" 98 5/6" 9 /8" 08 /" 5 9/6" 5
