Abstract
A pilot operated control valve has a body with an inlet and an outlet. A main valve poppet is movable within the body to selectively control flow of fluid between the inlet and outlet. The main valve poppet has a flexible diaphragm with a pilot passage therethrough which is opened and closed by movement of a pilot poppet. The diaphragm flexes due to a pressure differential that acts on the pilot poppet, which flexing compensates for adverse effects that the pressure differential has on the operation of the pilot poppet.
