ABSTRACT:
A pilot controlled, diaphragm actuated valve having simplified construction is provided which is capable of maintaining a variety of valve operating positions. In the preferred embodiment, the valve pin is controlled precisely with respect to the pilot opening in the diaphragm to permit modulation of the diaphragm position. Control of the valve pin is maintained through the use of a power assembly which positions the valve pin in accordance with some sensed system variable. The valve includes structure for reducing instability of the valve over the valve operating range.
