DN100 Aluminum Alloy Ball Valves
A manual ball valve in an aviation fueling system must provide predictable shutoff, stable sealing, and controlled operation across the temperature and pressure conditions found on the apron. The ATL48353201 is a DN100 manual aluminum ball valve developed for fuel-transfer assemblies, hydrant dispenser pipework, recovery-oil circuits, and other aviation fuel equipment where low mass and resistance to fuel exposure are required. The supplied product data specifies a working pressure of 1.0 MPa and a working temperature range of −40°C to 80°C. These limits define the basic selection envelope for the valve body and sealing system. The valve should be installed only after the system designer has confirmed pressure surge, fuel compatibility, connection dimensions, thermal conditions, and the required hazardous-area classification.

Application in Airport Fueling Equipment
Hydrant Dispensers
On a hydrant dispenser, a DN100 manual valve may serve as an isolation point within the product-fueling line or an associated service circuit. The design team should verify that the valve bore, pressure drop, handle clearance, and operating torque are compatible with the dispenser's flow-control architecture. If a deadman control switch is used, the manual valve should not be treated as an automatic substitute for the deadman shutdown function.
Apron Fueling Pipework and Service Assemblies
For apron pipework, the valve's aluminum body reduces component mass compared with heavier metallic constructions. This can be relevant on mobile equipment, hose-reel assemblies, and service modules where structural load and manual handling are design constraints. The installer must still confirm galvanic compatibility with mating flanges, threaded components, supports, bonding conductors, and protective coatings.
Fuel-Recovery and Slop-Tank Circuits
The valve can be considered for manual isolation in fuel-recovery circuits, including the return line from a recovery or slop tank to a main pipeline. In this service, the design review should address residual fuel, drainability, contamination control, vapor management, and the possibility of trapped liquid between isolation points.
Aviation Fueling System Integration
When integrated with a dry-break coupling, static bonding reel, filter-water separator, flow meter, pressure-control valve, or fuel contamination monitoring system, the ATL48353201 should be evaluated as one component in the complete fluid path. The valve's 1.0 MPa working-pressure rating must not be used as the maximum allowable pressure for an assembly unless every connected component, joint, hose, coupling, and instrument has an equal or higher approved rating.
