Abstract
A cylinder valve for use with a cylinder containing fluid under pressure. The cylinder valve has an aluminum valve body. The valve body has a flow passage extending through the valve body for permitting fluid to flow through the body to exit the cylinder and a vent passage for permitting fluid to vent from the cylinder. Nickel plating is applied to the vent passage. A dispensing valve is positioned along the flow passage. Thermal relief material in the vent passage blocks flow through the vent passage until a predetermined venting temperature is reached when the material changes to a flowable state to unblock the vent passage and allow venting of the cylinder through the vent passage.
