(1) (1) Electro magnet valve Electro magnet valve
Receive electric current from MCU and move the spool proportionally according to the specific
amount of electric current value.
(2) (2) Spool valve Spool valve
Is the two way direction control valve for pilot pressure to reduce main pump flow.
When the electro magnet valve is activated, pilot pressure enters into flow regulator of main pump.
