AP C2/C4 is used for an SB11 block for the open circuit (fixed pump).
The inlet and return lines of the flow are directed via AP C2/C4. AP C4 is identical
with AP C2, but with an additional N port for the pressure transmission.
Pressure compensator
according to the block-internal LS signal.
LS pressure relief valve
indirectly also the pressure in the block-internal P line by means of the pressure
compensator.
Primary pressure relief valve
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.
LS signal input : For linking an external LS signal via a shuttle valve to the
internal LS chain.
AP C2/C4 does not have a manual operating element or external control.
Unloading of the secondary pressure relief valve in the EHR11-EHS via AP C2/
C4 is not possible for design reasons (return flow RfB).
: Controls the inlet flow to the connected SB11 valves
: Limits the pressure at the inlet port
: Limits the pressure at the inlet port
