1CEEC35 - Motion Control and Lock Valve
Pilot assisted relief
30 L/min (8 USgpm) • 270 bar (4000 psi)
Description
Motion control and lock valves
give static and dynamic control
by regulating the flow into
and out of hydraulic actuators.
When installed close to an
actuator, the valve can stop
runaway in the event of hose
burst. The valves also give dual
thermal and overload relief
protection.
A low pressure tank or charge
line may be connected to the T
port to provide a make-up flow
to either actuator port.
Operation
The check section allows
free flow into the actuator
then holds and locks the load
against movement. The pilot
assisted relief valve section
will give controlled movement
when pilot pressure is applied.
The relief section is normally
set to open at a pressure at
least 1.3 times the maximum
load induced pressure but the
pressure required to open the
valve and allow movement
depends on the pilot ratio of
the valve. For optimization of
load control and energy
Performance Data
Pressure Drop
usage, a choice of pilot ratios
is available.
The pressure required to open
the valve and start actuator
movement can be calculated
as follows:
Pilot Pressure =
(Relief Setting) - (Load Pressure)
Pilot Ratio
A system of check valves
allows crossline relief for
dynamic applications with the
optional make up facility to
compensate for any change in
system volume.
Features
These valves provide complete
circuit control and protection in
a single valve body, reducing
installation time and cost.
Smooth, safe performance of
dual direction actuators.
Pilot Ratio
2.5:1 Best suited for extremely
unstable applications such
as long booms or flexible
frameworks.
5:1 (standard) Best suited for
applications where the load
varies and machine structure can
induce instability.
10:1 Best suited for applications
where the load remains
relatively constant.
