Carter Ground Fueling DivisionArgo-Tech Corporation - Costa Mesa HOSE END CONTROL VALVES MODELS 60129-1, 44646 & 47013 The Carter Hose End Control Valves (HECV’s) provide pressure limitation at the outlet to protect the aircraft while refueling. Three different pressure settings are available to tailor the control system to the customer’s requirements. The resultant control pressure curve is flat with little “droop” in pressure up to 300 U.S. gpm. Downstream surge pressure generated as a result of a rapid rise in downstream pressure (aircraft valve closure) is limited to 75 psi. Outlets are available to mate the HECV to any Carter or Thiem nozzle. Threaded inlet and outlet adapter fittings are also available for alternative installations away from a nozzle. A variety of inlet fittings are available to mate industry standard hose connections. FEATURES: 60129-1N46H HOSE END CONTROL VALVE For line mounted applications ❏ Lightweight - see Ordering Data for weights. ❏ Low pressure drop - see curve on following page. ❏ Direct Spring acting. ❏ Three pressure settings - 35, 45 & 55 available. ❏ Downstream surge pressure control - 75 psi max. ❏ Fail safe design. ❏ Mates directly to any Carter or Thiem nozzle. ❏ Variety of inlet quick disconnects available to mate industry standard hoses. ❏ Outlet fittings available to offer alternative installations away from nozzles. ❏ 60129-1 replaces 40680 (part number change only). ❏ Mechanical block out device, 61656, for system test and defueling now available - no connection to fuel pressure required. ❏ Over 35,000 HECV’s put into service in the past 24 years, no other unit has been so widely utilized.
