Ultra Low Pressure Drops
Long Life

The check valves were selected
for their performance [weight,
envelope, pressure drop, and
reliability]. Eaton used the latest
software techniques to optimize
flow path through the valve to
limit eddies and minimize acceleration
of the fluid which effectively
reduces energy loss. The
exclusion of polymers allows for
a greater range of temperatures
and fluids that this check valve
can operate under. The hardened
interior poppet valve gives
the check valve greater strength
and durability to have a long life.

Eaton Aerospace is proud to
present Aeroquip brand check
valves as a part of their high
quality line of fluid conveyance
products. Aeroquip brand check
valves are superior in attaining
ultra low pressure drops which
conserves energy and ultimately
saves operational costs over
the life of the program. The
check valves are currently utilized
on high pressure system
aircraft like the Airbus A380 and
Lockheed Martin F-35
