Solenoid operated control valve, hydraulic lift
His is an open centre directional control valve equipped with two solenoid valves governing the up and down movements
of the lift arms.
The two solenoid valves are piloted directly from the electronic control unit.
Never connect the solenoid valves directly to an electrical power source, as this would result in irreparable damage.
The hydraulic section of the control valve assembly comprises the following parts:
— 1 implement lift flow control valve
— 2 valve spool
— 3 implement down check valve
— 4 shock valve
— 5 rate of drop valve
— 6 check valve
— 7 down valve control element
— 8 implement down solenoid valve
The electrical section of the control valve assembly comprises the following parts:
— 9 lift arms Down solenoid valve
— 10 lift arms Up solenoid valve
