Y50 Baling pressure build-up solenoid valve
- limits the pressure in the tensioning arm circuit and thus controls the baling pressure.
- is controlled by the electronic box (the desired baling pressure is set by a potentiometer).
- when the power supply fails, the highest baling pressure is reached.
