Electronic control valve that combines the advantages of an excellent modulating, line pressure driven, hydraulic control valve with those of electronic control. In response to signals from the electronic controller, the valve changes its opening position per preset values programmed into the controller. The valve is double chamber actuated and is powered to fully open and close even at very low pressure. Both the valve’s opening and closing speeds are controllable and on-site adjustable.
