1CE120 - Overcenter Valve
Pilot assisted relief with check
-NJO64HQNtCBSQTJ
Description
Overcenter valves give static
and dynamic control of loads
by regulating the flow into and
out of hydraulic actuators. When
installed close to or within an
actuator, the overcenter valve
will stop runaway in the event
of hose burst and if open
center directional control valves
are used, will allow thermal
expansion relief of the hydraulic
fluid.
The overcenter cartridge is
ideal for mounting directly into
a cavity machined in the body
of the cylinder, motor or rotary
actuator. The cartridge can also
be mounted directly to the
ports via a specifically machined
body as part of a Hydraulic
Integrated Circuit or single unit,
or contained within one of our
standard line bodies.
Single overcenter valves are
normally used when the load
is unidirectional, for example
an aerial platform or crane
and dual overcenter valves
are used for controlling loads
in both directional for motor
applications or for cylinders
going over center.
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
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.
Pilot Ratio
3.5:1 (standard) Best suited for
applications where load varies
and machine structure can
induce instability.
8:1 Best suited for applications
where the load remains
relatively constant.
