ABSTRACT:
A fluid control valve having a valve body, a cage, and a flexible elastomeric diaphragm with a formed convolution to fully open the cage opening. An elastomeric diaphragm regulator with a flow diverter in the fluid flow path to reduce fluid flow separation and thereby reduce the required flow recovery area before pressure throttling. A raised knife edge seat located on the cage top in a position of stagnant fluid flow to reduce the build-up of contaminants on the seat. An elastomeric diaphragm regulator with a valve actuator coupled to a guided valve stem attached to the regulator diaphragm.
