1CE30 - Overcenter Valve
Pilot assisted relief with check
30L/min (8 USgpm) • 270 bar (4000 psi)
Operation
The check section allows 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
2.5:1 Best suited for extremely
unstable applications such
as long booms or flexible
frameworks.
5:1 (standard) Best suited for
applications where load varies
and machine structure can
induce instability.
10:1 Best suited for applications
where the load remains
relatively constant.

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.
