Controls. Electro-hydraulic E1 and E5

The HPV-02 E1 has two proportional solenoids and through the upstream signal circuit it combines the flexibility of electronic vehi-
cle management with the reliability of a pump control marked by its high operational availability. Precise and simple. Identical com-
mands always call for the same response in the machine, so no corrective action is required by the operator or the electronic system.
The HPV-02 E5 has two switching solenoids and thus sets the pump to either neutral or maximum swash angle of any direction.

E1P. Electro-hydraulic control with PCO
