2 and -H Series Service Regulators 0 Elster American Meter The Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications. General Information Outlet pressures between." W.. and PSIG are available. Operating temperature range is -0 F to 0 F (-0 to 6 ). Maximum flow rate is SFH (70.8 m /h). All models conform to ANSI ode B , and GA Service-Type Regulator Specification AN/GA-6.8-M9. Features Variety of interchangeable orifices and spring ranges 90 Degree (Right Angle), 80 Degree (Straight-Flow), or Offset Valve Body (See photo below) Wide range of valve body connection sizes 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 possible, a /" NPT plastic, 90 vent elbow (part number 780P0) and separate protective screen (part number 7000P07) may be screwed into the vent to provide the necessary protection. Elevation ompensation The E.. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.. 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. Full apacity Relief Valve Full capacity internal relief valve standard on all models. (See Performance Graphs on page 9) Splashguards UV stabilized, weather-resistant, resin device that protects the vent screen from Applications Model Number 8 8-H 8 8-H 8 w/ USSA 8-H w/ USSA splashes while providing a large external vent opening to keep regulators working properly. Safety Shutoff Devices 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 and 8-H. Spring Range Part Number " W.. to " W.. 70P00 PSIG to / PSIG 70P00 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.

Universal Safety Shutoff Assembly (USSA) USSA protects the downstream piping from both over- and under-pressure conditions by shutting off the gas flow at the inlet side of the regulator orifice.

8 and -H Series Service Regulators 08 Elster American Meter and -H Series Service Regulators - Other Technical Data Full-Open Regulator Relief apacity For sizing downstream relief valves, use the following formulas to determine the regulator full-open capacity: ritical flow rates Q = 0. x P G Sub-critical flows P Q = x h G ritical flow occurs when the absolute outlet pressure is less than about / of the absolute inlet pressure. Q P P h G Maximum capacity of regulator constant (see table below) Inlet absolute pressure (PSIA) Outlet absolute pressure (PSIA) Differential pressure Specific gravity of gas onstants /8" /8" x /6" /6" 7 /" 98 /6" 9 /8" 08 / 9/6" Maximum Recommended Inlet Pressure Size Inlet Pressure (PSIG) 9/6" 0 / 0 /8" 70 /6" /" /6" /8" x /6" /8" 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 ) Air Butane.0 0. arbon Dioxide. 0.6 Nitrogen Propane. 0.6 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 Example: If using propane and only having tables based on natural gas, the Specific Gravity onversion Factor is : (F g) = (F g) = 0.. (F g) = 0.66 Specific gravity of natural gas (0.6) Specific gravity of propane (.) Regulator Pressure Rating PSIG (8.6 bar) = Maximum recommended inlet pressure for normal service. Maximum recommended pressure may vary with 7 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. 0 PSIG (. 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.
