Abstract
A diaphragm actuated-rod operated valve assembly adapted for installation in a fluid flow is disclosed comprising a one-piece elastomeric valve-spring-seal member which is operated by the push rod and has only a static seal and in addition is provided with internal support such as to prevent an otherwise collapsible portion of the valve from grabbing the operating rod as a result of external pressure and thereby inhibiting valve operation.
