Hydraulic directional spool valve
400 bar, 160 lpm | HSR series
HAWE Hydraulik
connection (type HSL), manifold mounting (type HSF) or as valve banks
(type HSR). These valves are utilized to control the direction of movement
of hydraulic consumers. All of them are indirectly electro-hydraulically
actuated. The control fluid demand is either taken internally from the
main circuit or fed externally from a separate control oil circuit.
These valves are equipped with adjustable thread type throttles (exception
HSRL 3), prolonging the shifting operation, thereby preventing harsh
shifting, which might cause pressure
surges due to high pressure
or consumer flow. The valve banks
come with a connection block
which optionally incorporates e.g.
an idle circulation valve, a
pressure limiting valve or a pressure
reducing valve (control fluid
supply for high primary pressure).
Type HSRL 3 gives provision to
select different pressure stages
during operation
