Proportional Valve Driver, two PWM solenoid outputs, in sealed plastic enclosure.
The Proportional Valve Driver is an electronic device powered by a regulated or unregulated DC supply or a battery (in mobile applications), it receives small power signals from a potentiometer, joystick, PLC, analogue output card, computer or other control device and delivers high power controlled current to the solenoid of a proportional valve in order to regulate through pressure or flow the motion of a hydraulic actuator.
Advantages Of Using Our Drivers
- Digital display confirms proper operation at a glance: it shows the input signal directly in Volts or mA, the output current directly in Amps or the driver settings names and values
- Only need one part number for input signals 0-5V, 0-10V, 0-20mA or 4-20mA, for coils rated 1A, 2A or 3A and power supply 12V or 24V
- The only tool you need to install and tune-up is a standard screwdriver
- Better linearity and control
- More effective dither
- Easy to read and duplicate settings
- Diagnosis possible even over the phone
- Insensitive to vibrations
- Wider operating voltage and temperature, output current, dither frequency range, independent up & down ramps
- Technical support by the designer, available 24/7 on request
Benefits And Features
- Versatile digital design
- Large, easy-to-use adjustments and three-digit seven-segment LED display
- Wide range of supply voltage
- Electronic limiting circuit / short circuit proof
- Load can be connected & disconnected live
- Protected against wrong connection
- Energy-efficient PWM circuit, no heat sink is required

Set-Up Procedure
At power up, you may rotate the left side control to select the variable, displayed: Ain (A input), Aot (A output), bin (B input) or bot (B output), the actual solenoid output current directly in Amps or the command input signal in V or mA, corresponding to the input range pre-selected. To enter setup mode, rotate right side control ; the display will show the settings sequentially: AH1, AJ9, ALO, AUP, Adn, Adb, Ain, bH1, bJ9, bLO, bUP, bdn, bdb, bin, db, dF, in, di and SA.
When you reach the setting that you want to modify, rotate up or down to the desired value. To modify another setting, rotate and repeat. The Driver is fully functional during the set-up procedure with any adjustments effective immediately (except the input range selection that becomes effective only after saving). In order to write the new settings in the memory and return to normal mode of operation, rotate until the display shows SA and then rotate one full turn. If you do not want to keep the new settings, simply power down without saving.
