1CEBL153 - BoomLoc Valve
Hose burst protection, line mounted with independent pilot control (Ref. ISO 8643)
150 L/min (40 USgpm) • 350 bar (5000 psi)
Description
These overcenter valves
are suitable for use on the
boom and dipper cylinders
of an excavator to help the
manufacturer or user comply
with standard ISO8643.
They were designed to give
relief, load holding and hose
failure protection to systems
where a pilot system controls
the directional valves.
Operation
By connecting the pilot line in
parallel with the spool valve
pilot, the high pilot ratio allows
the valve to open just prior to
the spool valve, ensuring that
the valve does not interfere
with the normal operation of
the machine. Both the pilot
and the relief sections are
unaffected by back pressure,
enabling the service line reliefs
to operate normally, without
interfering with the spool
valve control as it meters the
return flow. In the event of
hose failure, the control will
be passed from the main
spool to the overcenter valve,
maintaining control of the
cylinder.
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
This is a compact design
with good dirt tolerance.
Hardened poppets and seats
provide excellent load holding
characteristics with all the
advantages of the cartridge
insert.
