Direct drive servo valves
January 1st 2008 Following the adoption of the
Moog E050 Miniature Cartridge
Direct Drive Valve (DDV) by the
Motorsport industry, Moog now
offers the technology for servo
valves and servo-proportional
valves to provide high performance
and precision motion control in
other industry sectors.
The cartridge design permits highdensity
fitting for applications
where multiple valves are required
to be mounted on a single
manifold or in industries where
weight and space are at a
premium. The weight of the
cartridge DDV is said to be only
one third of that of the standard
steel-bodies industrial version.
Servovalves using DDV technology
are more energy efficient than a
conventional two-stage servo as
they have no pilot stage hydraulic
flow. In the motorsport developed
cartridge DDV servovalve, the
spool leakage has been reduced
by a factor of 20 compared to the
standard valve. More articles from Moog Controls: |
