Hydraulic systems - Main control valve
Oil flow pump P1
The oil flows through port P1 into the main valve and then to the primary pressure-limiting valve of pump P1.
The oil flows through the two parallel channels P1 and P01 to the control spools and to the valves.
Channel P1 directs the oil flow through a valve of the bucket parallel circuit to the bucket control spool.
Channel P01 directs the oil flow to the travel spool, from where a branch-off leads to a load holding valve. The load-holding valve opens and the oil is available at the travel spool, ready to be recalled. The oil flow by-passes the stabilizer spool and reaches the boom spool. A branch-off ahead of the spool directs the oil flow also through another load holding valve to the boom spool. The oil flows then to the bucket spool. The oil is then available to the bucket spool via a load-holding valve. The oil flow reaches then the dipper spool. Also here a branch-off delivers oil to the dipper spool through a load holding valve. Two parallel channels P2 and P02 direct the oil flow through the main valve.
