Abstract
A gas valve body with a first flow chamber and, a second flow chamber including and a main valve positioned in line and between the first flow chamber and the second flow chamber. The main valve can be opened by creating a pressure differential across the main valve. An electrostatically controlled pilot valve is provided for controlling the pressure differential across the main valve for 'on-ff' operation. The electrostatically controlled pilot valve may also be operated to 'modulate' the pressure differential across the main valve along a range of pressure differential values.
