Description

Directional Valve 3/2 is used as an unloading valve for the LS-line in a load-sensing system with a variable displacement pump. When assembling a variable displacement pump on a coupling independent power take-off (engine power take-off) where the pump is running constantly, the pump signal line must be relieved to tank when the pump is not used. This is to prevent pressure build-up in the signal line causing the pump to angle out and start working (pump oil).
