Instruction Manual Form 1095 October 2009 1305 Series 1305 Series Pressure Reducing Regulators Fisher regulators must be installed operated and maintained in accordance with federal state and local codes rules and regulations and Emerson Process Management Regulator Technologies Inc instructions If the regulator vents gas or a leak develops in the system service to the unit may be required Failure to correct trouble could result in a hazardous condition Call a gas service person to service the unit Only a qualified person must install or service the regulator Introduction The 1305 Series regulators are direct operated pressure reducing regulators that resist hydrate formation and regulator freeze up Regulator freeze up resistance occurs as the pipeline gas warms the finned inlet adaptor and the orifice area As the gas cools within the inlet adaptor due to pressure drop and volume expansion the warm inlet adaptor helps keep the gas temperature above the freezing point of water and the hydrate formation temperature The regulators are suitable for service with natural gas air propane and other gases compatible with the internal parts Type 1305C 1 NPT inlet and 1 4 NPT outlet connections 5 64 inch 2 0 mm orifice diameter Three springs provide 0 to 225 psig 0 to 15 5 bar reduced pressure ranges Figure 1 1305 Series Regulator with Tapped Lower Casing Connection Type 1305D same as Typ
