These valves are designed to control the direction and oil flow rate based on the degree of command signal supplied to the On-Board Amplifier. In event of a loss in electrical power, the centering springs will return the valve spool to the center position.
The On-Board microprocessor controls all the valve functions and is pre-set to optimal valve performance. In-field adjustments can be performed via software to customize the parameters based on your application needs.
A variety of manual overrides are also available.
