1CEECSH150 - Motion Control & Lock Valve
Pilot assisted relief with brake shuttle
150 L/min (40 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.
The shuttle valve provides a
signal from the high pressure
side of the actuator to release
sprung applied brakes.
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
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
This valve provides complete
circuit control and protection
as with the standard motion
control valve but has the
addition of a brake release
shuttle and brake port
contained in a single body.
Pilot Ratio
3.5:1 Best suited for applications
where load varies and machine
structure can induce instability.
