AP C6 is used in an SB11 block for the closed circuit (variable displacement
pump). The inlet and return lines of the flow are directed via AP C6.

Pressure relief valve : Limits the pressure at port
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.
Rx-R check valve : Protects the block-internal EHS pilot oil return line Rx against
pressure peaks from block-internal return flow R.
