Safety blocks built
November 1st 2008 A new range of accumulator safety
blocks from Parker Hannifin are
designed for use in a range of
critical hydraulic applications to
help minimise system build and
maintenance times and reduce
costs while improving safety.
The SBA series makes it simple
to protect, isolate and discharge a
hydraulic accumulator from a
single unit. Each SBA safety block
incorporates shut-off, pressure
limiting and pressure release
functions in a compact and robust
housing, with each block rated for
use in systems operating to 350bar.
Features include a modular
design of tamper-proof pressure
relief valve that can be specified in
a range of pressure settings. The
valve can be changed easily
without disconnecting or removing
the block, simplifying changes to
system pressures and making it
easier for OEMs to specify and
stock component parts.
The integrated shut-off valve
allows an attached accumulator to
be isolated and then safely
discharged to tank; this can be
done directly using a lever-operated
discharge valve on the block; or
remotely by a separate electrically
controlled discharge valve. More articles from Parker Hannifin Ltd: |
