Averill Park, NY March 29, 2016 -- We are now shipping ECVs with a new logic board. The new ECV board has:

  • Higher resolution for smoother control
  • Adaptive noise filter dynamically eliminates dithering
  • Switch options for isolated/grounded control signal and more

Our new microcontroller has a 10 bit AD converter instead of an 8 bit converter for a 4X improvement in resolution, from 1/2 percent to 1/8 percent.

We improved our digital noise filter by introducting an adaptive filter. Every second, the filter measures the dither of the valve and adjusts the filter parameters until the dithering is eliminated. To reset the filter, simply cycle power. A switch on the board turns off the adaptive filter, leaving a mild digital filter in place.

The new boards are 100% compatible with all ECV valves and are drop in replacements. The boards are also available as a spare part, PN 11299.

Please contact us if you have any questions.
