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.
For installation on Carter 64348 or 64349 Nozzles either in conjunction with a Carter 64015 Ball Valve or when a dual HECV installation is desired on a Carter nozzle.
