Refueling/Defueling Pantograph

• Maximum Protection Against Environmental Leakage

• Higher Flow Rates and Shorter Refueling Times

• Stainless Steel Piping

• All Stainless Steel Non-Lubricated Swivel Joints

• Heavy Duty Wheels and Casters

• Galvanized Steel Support Structures

• Spring Tension Counterbalances

• Low-Profile and High-Lift Designs Available

The Cla-Val Model 850AF Pantograph is
the ultimate aviation fueling device. Hard­piped to eliminate the liabilities associated
with rubber hose, the Cla-Val 850AF
Pantograph sets the industry standard for
maintenance-free operation, higher flow
rates, and design versatility in refueling
systems.
The structural integrity of the Cla-Val
850AF Pantograph ensures maximum
service life and maintenance-free
operation. It is constructed of stainless
steel piping and valves connected by
rugged, multi-axis swivel joints for easy

maneuvering. These high-performance
swivels require no lubrication and retain
their integrity during the most demanding
applications, including towing the
pantograph from site to site.
The Cla-Val 850AF Pantograph achieves
higher flow rates and shorter refueling
times than refueling systems that utilize
hoses or hose reels. The lower internal
flow resistance of pipe allows the
pantograph to deliver fuel with a lower
overall drop in pressure.
The Cla-Val 850AF Pantograph offers
designs for small loading racks, low-wing

or fuselage refueling, and even high-lift
designs for refueling the largest aircraft
flying today. The pantograph extends to
reach remote delivery points and then
retracts for compact storage. It can be
located above ground or mounted in
below-grade pits. It can be configured for
permanent installation or as a tow rig for
portable applications. Portability is
enhanced by the use of heavy-duty
casters and wheels, making the Cla-Val
850AF Pantograph easy to maneuver for
fast refueling or defueling of fixed-wing
aircraft, helicopters, or tank trucks.
