2015 Maxitrol Company. All Rights Reserved. DRAFT 09.18.2013 38 Pipe Sizes.................................... 1 to 3 threaded connections with NPT or ISO7-1 threads. 4 125 lb. flange 220J only. Housing Material........................ 220D 220E 220G 220J aluminum. Mounting.................................... Mount in an upright position only. NOTE All Maxitrol gas pressure regulators should be installed and operated in accordance with Maxitrol Safety Warning Instructions see GPR_MI_EN.ES. Gas Types.................................... Suitable for natural manufactured mixed gases liquefied petroleum gases and LP gas-air mixtures. Maximum Inlet Pressure............. 10 psi 68.9 kPa Flow Rates................................... up to 50000 CFH 1416 m3 h Emergency Exposure Limits......... 25 psi 170 kPa Ambient Temperature Ranges...... -40 to 200F -40 to 93C Sensing Taps................................ Three positions can be tapped and plugged for measuring pressure. The fourth position is used to supply inlet pressure to the pilot regulator. Remote Sensing........................... 220D 220E 220G models may be ordered with remote sensing. The internal sensing tube is omitted and external sensing taps are provided. Add suffix letter R to model number when ordering. NOTE 220D 220E 220G 220J are not CSA certified. NOTE L models available for outlet pressures under 1 psi 6.9 kPa. The 220 series uses a servo-operated design rather than a spring-loaded design and can deliver higher outlet pressures than conventional spring-loaded models. The main diaphragm of the model 220 is loaded with gas pressure instead of spring pressure. A small pilot regulator located in the upper housing accurately controls this gas pressure. When the regulated outlet pressure of the servo regulator is changed by spring adjustment the outlet pressure of the 220 main regulator will be changed proportionately. Applications include industrial furnaces and ovens. 220 D 220 SERIES Pilot Loaded Design Specifications
