The PN160 Forged Steel A105N Bellow Seal Globe Valve is an ultra-high-pressure safety valve designed for zero-leakage performance. The A105N forged body provides the structural density required for 160 bar service, while the Butt Weld (BW) ends ensure permanent piping integrity. Its core feature—a metallic bellows—creates a hermetic seal that eliminates fugitive emissions, making it essential for high-pressure thermal oil, toxic gases, and steam systems.
