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.

Technical Information
  • Nominal spring settings (maximum pres-sure limits will be 5 psi greater than spring) - 35, 45 & 55 psi available.
  • Surge pressure control - 75 psi maximum with 0.5 second valve closure minimum.
  • Lock Up Pressure - 10 psi maximum over spring setting.
  • Pressure Limitation - 5 psi over spring set-ting with inlet pressure up to 100 psi
  • Hysteresis (difference in pressure limits between increasing and decreasing flow rates) - pressure limits with decreasing flow rates will normally be slightly greater than for increasing flow rates.
  • Defueling possible through unit, however block out device required to maintain maximum flow. Use Carter Block Out Device 61656.
  • 61656 Block Out Device recommended if system secondary control valve is to be checked.
