Mainly used in construction machinery
and
other mechanical forms
of
hydraulic circuits that
are
decentralized by gravity, it can produce a
balance with the changing load
to
ensure that the load stops reliably
in a
certain position, and control
the
balance of the movement when
the
load
drops, and prevent the damage of
structural parts, hydraulic
parts, pipelines and other
parts caused by the
overspeed drop of the load.Model:25330B,5160A,5160AF1,25160A,25160AF,25160B,25160BF,25220B,25220BFandothermodels
