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 Spool Position Sensor circuit improves the overall valve performance by reducing hysteresis and improving response times.
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. The valves with internal pilot are available also with a pressure reducing valve.
