2 EATONAerospace Group TF100-105D May 2013 Eaton’s Carter product line includes several standard underwing refueling nozzle models. A nozzle derived from earlier Model 64200 has been introduced, primarily for those airports that have extremely heavy-duty requirements. Model 64250 Heavy-Duty Refueling Nozzle, in addition to being designed for rugged, heavy-duty use, has several new features outlined below. Features yy Easier swivelling under all conditions. Swivel independent of quick disconnect. yy Connects to 3-lug international standard aircraft adapter yy Designed in accordance with new SAE design specification for commercial nozzles AS5877 yy Self-adjusting pressure loaded nose seal. Leak free under extreme side loads, worn adapters and extreme temperatures. yy Uses same accessories as earlier 64200 and 64348 models. All accessories now have stainless steel wear ring in swivel ball joint. yy Lead-in ramps (interface with aircraft adapter lugs) of high strength aluminum for longer life yy Positive mechanical interlock — nozzle cannot be opened until connected to aircraft; cannot be removed from aircraft in open position yy Interlock mechanism internal to nozzle body yy No collar or other moving parts on exterior of nozzle with the exception of the operating lever yy Two threaded ports in nozzle body for simultaneous vacuum breaker and product sampling fitting installation are standard yy Lightweight and most rugged of any Eaton nozzle yy Modular construction with use of bolt flanges minimized yy 2, 2½ and 3-inch NPT and BSPP and 3-inch JIS threaded quick disconnect (QD) inlets available yy Optional 40, 60 & 100-mesh screens retained with snap rings for ease of removal yy Operating lever replaceable from exterior of nozzle and is made of less expensive, more ductile material. Also backed up with boss on nozzle body to prevent bending. yy 35 psi (2.413 bar), 45 psi (3.103 bar) & 55 psi (3.792 bar) Hose End Control Valves (HECV) available yy Dry break or ball valve for easy strainer inspection available yy Low pressure drop yy Optional bonding cable and vacuum breaker yy Redundant safety lock on the QD yy Replaceable knob on operating handle eliminates razor sharp wear patterns prevalent on competitor’s nozzles yy Options include a “U” bracket for nozzle stowage and one piece stirrup handle with stowage capability. No need to use an aircraft adapter as a stowage device. Design Concepts Envelope Dimensions Dimensions shown in inches (millimeters)
