FLUID REGULATORS HAVING CORRUGATED DIAPHRAGMS

摘要

Corrugated diaphragm apparatus for improved cycle life of a diaphragm are described herein. One described example apparatus includes a valve body having an inlet and an outlet to allow fluid to flow therethrough, a backing plate disposed within a bonnet and coupled to the valve body, and first and second diaphragms. Each diaphragm has a corrugated profile and is in a stacked configuration. The diaphragms are operatively coupled to the backing plate and each of the diaphragms is clamped between the valve body and the bonnet proximate a peripheral edge of the diaphragm.
