Abstract
A cylinder valve for use with a cylinder containing fluid under pressure includes a valve body configured for releasable connection to the cylinder. The valve body has a flow passage extending through the valve body for fluid communication with an interior of the cylinder when the valve body is connected to the cylinder. A valve in the flow passage is movable between open and closed positions. A vent passage is in the valve body and is separate from the flow passage. A temperature relief insert is in the vent passage. The insert includes an insert body, a bore through the insert body, and a thermal relief material in the bore blocking flow through the bore until a predetermined venting temperature is reached. The valve body does not contain brass and the insert body is brass covered by a metal plating not containing brass.
