Description
MANUFACTURER: Meggitt Fuelling
Jet Level Sensor, Internal Valves – Meggitt Fuelling
F614 4-inch valve, F620 6-inch valve
The Meggitt bottom loading system designed for aircraft refuellers utilizes the unique jet level sensor in conjunction with an internal valve. This system combines automatic bottom loading with off-loading (aircraft refuelling) through one valve.
Available in 4-and 6-inch sizes, the internal valves are built with modular pilots to allow the use of the internal valve as a standard off-loading valve only with easy conversion to bottom loading at a later date.
