Meggitt hydrant valves are in use world-wide, refuelling aircraft of all descriptions. Meggitt manufactures hydrant valves for use as primary pressure controls or as simple air or lanyard operated shutoff valves. These hydrants are available for use with any hydrant coupler on the market whether it is 2.5 or 4-inch API 1584 style.
PRESSURE CONTROL HYDRANT VALVES
Meggitt pressure control hydrant valves are designed for use as the terminating valve in an airport hydrant fueling system. The hydrant pressure control valve provides a self-sealing connection between the hydrant and mating coupler on a fuel servicing vehicle. Flow through the system is started with the application of a preset air pressure supplied by the servicing vehicle. The hydrant valve maintains a constant nozzle pressure at the aircraft as the aircraft is being refueled. All Meggitt pressure control hydrant valves will shut off automatically if system demand exceeds a preset limit,safeguarding against fuel loss in the event of insecure connection or line rupture. An optional feature provides a selected two flow rate setting for this excess flow protection. Any hydrant valve can be furnished less this feature if so desired. Several modifications of the hydrant valve are available in both 4 x 4 and 4 x 2.5
