ABSTRACT:
The reduction valve (1) comprises an activating spindle (12;42) which by a control handle on a pivotable shaft (8) and an eccentric spigot (11) is displaceable for opening of a self-closing valve (4) in a gas container valve (3) for a bottle for liquified gas. A section (18;49) of the activating spindle or of the self-closing valve (4) is made from a material having a low yield temperature, such that heating thereof, for instance caused by fire, causes the material to yield, whereby the activating spindle (12;42) or the self-closing valve (4), respectively, is shortened under influence of the biasing force from the spring (6) of the valve (4), whereby the valve (4) closes.
