Kind Code:
B2
Abstract:
A fluid control valve (10,74,114) having a valve body (12,76,116), a cage (20,84,124,154), and a flexible elastomeric diaphragm (38,88,144) 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 (134) 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 (188,198) attached to the regulator diaphragm.
