Abstract:
A valve having secondary spring force containment includes a valve body featuring an opening with a valve closure member sized to close the opening. A stem has a first end connected to the valve closure member. A proximal spring seat is positioned adjacent to the valve body, A distal spring seat is mounted on the second end of the stem. A spring is positioned between the proximal and distal spring seats so that the valve closure member is urged into a position where the valve body opening is closed. A hollow rod is attached between the proximal and distal spring seats to provide secondary spring force containment with the stem passing through the hollow rod.
