Where measurements are critical request certified drawings. We reserve the right to change specifications without notice.
Note: This valve has been
designed to eliminate
instability from flexible boom
applications or where the load
induced pressure varies
greatly. To get the best
results, the settings should
be adjusted for each
application and then
factory set for production
quantities. Please contact

1CEL140 - Overcenter Valve
Counterbalance, pilot assisted relief with check
140 L/min (37 USgpm) • 380 bar (5510 psi)
Description
The 1CEL overcenter valve
performs all duties of a regular
overcenter but maintains
a counterbalance pressure
to provide dampening of
cylinders when there is a
rapid loss in stored pressure.
This counterbalance pressure
reduces as the pilot pressure
increases. Typical applications
include extension cylinders on
telescopic handlers where it
is important to have a smooth
operation when retracting
from full extension.
Operation
The check section allows free
flow and then locks the load
against movement. The pilot
assisted relief valve section
will give controlled movement
when pilot pressure is applied,
maintaining a counterbalance
pressure to prevent initial
pressure loss and therefore
instability. The total pressure
setting will normally be set
at 1.3 times the load induced
pressure. The counterbalance
pressure reduces as the pilot
pressure increases.
Features
Cartridge is economical and
fits simple cavity. Allows quick,
easy field service - reduces
down time. Interchangeable
with pilot check valve of a
similar size.
