The
C6
connecting plate is used for SBx4 blocks with or without central connecting
plate.
Shuttle valve with spring pretension :
Discharges the higher LS pressure from the
block-internal channel Y and
to port
. The spring pretension prevents pressure
build-up in
if port
is not occupied.
Pressure relief valve :
Limits the pressure at port
and indirectly also the
pressure in the block-internal
P
line.
NOTICE!
The pressure relief valve with its short response time and low flow is
applied for limitation of the pressure peaks in the supplied flow.
