The inlet and return lines of the flow are directed via the C4connecting plate.
Pressure compensator
: Controls the inlet flow to the connected SBx4 valves
according to the block-internal LS signal.
LS pressure relief valve
: Limits the pressure at the inlet port and indirectly also
the pressure in the block-internal P line by means of the pressure compensator.
Primary pressure relief valve
: Limits the pressure at the inlet port and indirectly
also the pressure in the block-internal P line.
NOTICE! The primary pressure relief valve with its short response time and low flow
is applied for limitation of the pressure peaks in the supplied flow.
