The triple-offset geometry allows the disc to move away from the seat<br \/>\nduring operation, minimizing friction and helping protect the sealing surfaces.<\/p>\n<p>The valve uses a multilayer metal sealing arrangement for applications where conventional<br \/>\nsoft-seated butterfly valves are not suitable. It is commonly selected for gas, vacuum,<br \/>\nsteam and compatible industrial media in power generation, petrochemical, coal chemical,<br \/>\nmetallurgy, pulp and paper, textile dyeing and light industry.<\/p>\n<h2 style=\"color: #123a5a; font-size: 26px; margin: 28px 0 16px;\">Main Features<\/h2>\n<ul style=\"padding-left: 22px; margin-top: 0;\">\n<li>Triple-offset disc geometry with reduced friction between the disc and seat.<\/li>\n<li>Multilayer metal seat for high-temperature and high-pressure service.<\/li>\n<li>Reliable shut-off for high-cycle gas and vacuum applications.<\/li>\n<li>Pneumatic actuation for fast quarter-turn operation and automation.<\/li>\n<li>ISO 5211 top mounting platform for actuator installation.<\/li>\n<li>Precision-cast one-piece body structure.<\/li>\n<li>Self-lubricating bearing design helps reduce operating torque.<\/li>\n<li>Graphite packing option for high-temperature stem sealing.<\/li>\n<li>Stainless steel, duplex, super duplex, titanium, nickel alloy and Monel materials available.<\/li>\n<li>Manual, worm gear and electric operation available on request.<\/li>\n<\/ul>\n<h2 style=\"color: #123a5a; font-size: 26px; margin: 28px 0 16px;\">Triple-Offset Metal Sealing Design<\/h2>\n<p>The triple-offset construction is designed so that the disc and seat separate quickly<br \/>\nonce the valve begins to open.
