The pressure compensator DWM08130Y
is a normally open, direct-acting, spring
loaded ow control valve.
By maintaining a constant differential
between inlet and outlet pressure of an
orice (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 orice cross-section. The downstream
pressure compensator can, for example,
be used when lowering 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 Versions available for different control pressure differentials and for ow rates up to
max. 30 l/min
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
z Internal venting of the load sensing line
