Abstract

A spring force assembly a sleeve coupled to a valve stem and configured to move axially along a valve axis responsive to movement of the valve stem. The spring force assembly also includes a collet positioned circumferentially about the sleeve, wherein an interface between the sleeve and the collet is used to transmit force from the sleeve to the collet. The spring force assembly further includes a spring configured to be compressed responsive to movement of the collet. Downward movement of the collet, responsive to movement of the sleeve, is configured to engage a portion of the actuator to mechanically lock the spring into a compressed position and to maintain the spring in the compressed position until upward movement of the sleeve, relative to the collet, releases the collet.
