TIC Liner 3000 with Communicator Individual functions Description of function: No volume flow flowing, the solenoid valves are not actuated Due to the two face-end pressure springs, the spool is positioned so that port P is blocked (see diagram). Solenoid coil is active The solenoid coil is actuated proportionally by the CCU (CLAAS Control Unit). The spool can be positioned in any position, depending on this actuation. The active solenoid coil actuates the spool against the face-end pressure spring. Volume flow flows from channel (P) via the spool to the consumer port. At the same time, the volume flow from the other consumer port flows into the tank (T) via the spool. 12/03 Lin-h-Kap2 2-5
