The effect used to vibrate a proportional valve spool is
called dither. Dithering can offset the hysteresis. The dither
frequency is specific to each valve and application,and the valve
amplifier, or controller, will have an adjustable dither frequency.
Hence, please purchase our amplifier togehter with the proportional
valves.
