The lighter gas valve with a metal stem presents its own array of advantages. The metal construction, typically made from durable alloys, endows the valve with enhanced strength and rigidity. It can withstand higher pressures and more extreme conditions compared to its plastic counterpart. The metal stem conducts heat more efficiently, which can be beneficial in certain applications where rapid ignition or heat dissipation is required. This valve is often favored in industrial or professional-grade lighters that need to endure heavy usage and harsh environments. It also imparts a more premium and robust feel to the lighter, appealing to users who value durability and performance.
