Cla-Val 341GF / 342GF Severe Duty Refueling Nozzle

The Cla-Val 341GF/342GF series are pressure refueling nozzles designed for single-point aircraft refueling and bottom loading of fuel tankers. These nozzles interface with MS24484 aircraft adapters and comply with SAE-AS5877. The 341GF variant is primarily configured for military service, while the 342GF is intended for commercial refueling operations.

Operation and Interlocks

The nozzle incorporates two mechanical safety interlock systems:

  • Primary interlock: Prevents nozzle actuation unless properly engaged with the aircraft adapter.
  • Secondary interlock: Reduces risk of mis-engagement with worn adapters.
  • Removal interlock: Nozzle cannot be removed until the operating lever is fully returned to the closed position.

Square register pins ensure positive alignment with adapter slots, which is critical in high-frequency connection/disconnection cycles.

Construction

Construction utilizes aluminum and stainless steel. The stainless steel bayonet ring is cast within the aluminum collar. The operating shaft spans the full flow cross-section and is supported by an internal wall, which also aligns flow and minimizes pressure drop.

Configurations

Available options include:

  • Standard, long, 7° or 15° handles
  • Grounding cable and stowage bar
  • Vacuum breaker
  • HEPCV 35, 45, or 55 psig with flanged outlet
  • D-1 elbow, D-2 straight, or D-3 variable swivel inlet
  • 40, 60, or 100 mesh strainer
  • Standard QD or dry break quick disconnect
  • 2”, 2.5”, or 3” NPT/BSPP threads

Applications

  • Airport hydrant dispensers
  • Refuellers and carts
  • Aircraft pressure fueling
  • Bottom loading of fuel tankers
  • Jet A-1 and aviation fuel service (verify line component compatibility)

FAQ

When is HEPCV required?
When hose-end pressure control is needed at the nozzle connection point.

When to select dry break QD?
For installations where disconnection must minimize fuel leakage and trapped product at the line end.

Description

The Cla-Val Model 341GF/342GF Severe Duty Nozzle is a refueling nozzle for pressure fuel servicing of aircraft, and for bottom loading of tank trucks.

To ensure maximum safety during refueling, the Cla-Val 341GF/342GF Nozzle has primary and secondary interlock systems. The primary interlock ensures that the nozzle cannot be opened when it is not connected to an aircraft adapter. The secondary interlock protects the nozzle from hazards of interfacing with badly worn aircraft adapters. Even when used with a badly worn adapter, the nozzle is safer because it uses square register pins that provide positive alignment with the square slots in the adapter. In addition, the nozzle cannot be removed from the adapter until the operating lever is rotated to the fully-closed position.

To achieve maximum strength and durability, the Cla-Val 341GF/342GF Nozzle uses a stainless steel bayonet ring cast within the aluminum collar of the nozzle. The crank shaft of the nozzle extends across the entire width of the interior flow path and is supported from end-to-end by a structural wall that splits the flow path. This wall supports the crank shaft while straightening the flow and keeping flow resistance as low as possible. To reduce aircraft refueling times, the flow resistance though the Cla-Val 341GF/342GF Nozzle has the lowest head loss, which means it can fill an aircraft faster than any other nozzle.

341GF Nozzles are configured for military service and 342GF Nozzles are configured for commercial refueling service.
