Abstract
A radial diaphragm valve includes a diaphragm having an elongated stem that is threadably or otherwise installed on an actuator piston. The elongated stem is slideably received in a bore formed in the actuator housing, and includes a circumferential recess that receives a seal. The seal provides a backup seal function separating the process fluid from the interior region of the actuator.
