The pressure compensator DW05830V
is a normally open, direct-acting, spring
loaded ow control valve which operates
smoothly.
By maintaining a constant differential
pressure between inlet and outlet of an
orice (ports 1 and 3 of the pressure
compensator), a constant ow rate is
maintained (independently of the load
pressure). As soon as the pressure
differential exceeds the value pre-set by
the spring force, the control piston reduces
an orice cross-section.
The pressure compensator can, for
example, be used when raising variable
loads at the same velocity. Together with
a proportional ow control valve it can
be used as a 2-way proportional ow
regulator.
In a load sensing system in which several
consumers are operated in parallel, each
one can be individually speed-controlled.
Features
z Used to control the ow rate of consumers independently of the load pressure
z Excellent stability throughout pressure and ow range
z Excellent dynamic performance
z All surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and ground components to
ensure minimal wear and extended service life
z Rigid design using one-piece body minimizes the effect of eccentricities in cavity and
maximizes reliability
z Reliable operation due to integral stroke limitation
