The invention relates to a gas bottle valve (10) having a valve housing (16) on whose head part (12) there can be placed a pressure regulator (A) for the extraction of liquid gas. Said pressure regulator has a control pin (B) for operating a non-return valve (20). A spring-loaded closing body (28) projects into a sliding guide (26) of the head part. A first sealing ring (30) is arranged on the closing body or on the sliding guide and a second sealing ring (32) is arranged downstream of said sealing ring (30) in the flow direction. The head part (12) can be integral with the valve housing or can be a detachable component. The closing body (28) is preferably reduced in diameter and guided in the sliding guide (26) with a close fit, but with radial play on the outer opening (40) of the head part (12). The closing body (28) can be guided in a sliding sleeve (42) at least by a collar (34). <IMAGE> |
