ABSTRACT:
A valve having a normally non-rising stem (30a,b) journaled between bearings (38a,b 40a,b) is equipped with an energized drive spring (56a,b) for positively engaging backseat seal surfaces (64a,b, 66a,b) upon melting of a fusible ring (52a,b). The spring (56a,b) is compressed axially against the retainer (46a,b) by the cooperative action of the compression nut (58a,b) and the tubular spacer (49b, 50a,b), thereby normally avoiding undesirable axial thrust on the bearings (38a,b, 40a,b).
