Triple Offset High Temperature Butterfly Valve

ALIS Valves offers Triple Offset High Temperature Butterfly Valves for industrial applications requiring reliable flow isolation and durable performance under elevated temperature conditions. These valves feature a triple-offset disc and seat geometry designed to minimize friction between the sealing surfaces during opening and closing. The three-offset arrangement allows the disc to disengage from the seat as the valve opens, helping reduce seat wear, operating torque and friction during repeated cycles. Depending on the specified design, metal-to-metal sealing surfaces, heat-resistant body and disc materials, and suitable high-temperature packing components can be selected to support operation under demanding thermal conditions. These valves can be configured with manual, pneumatic or electric actuators, provided the actuator arrangement is suitable for the operating temperature and installation environment.

Triple Offset High Temperature Butterfly Valves are used in power generation plants, refineries, petrochemical facilities, steel manufacturing, thermal oil systems, steam pipelines and other industrial processes involving elevated temperatures. Depending on the selected materials, pressure rating and sealing configuration, they can be specified for compatible liquids, gases, steam and high-temperature process media within their rated operating limits. Important selection factors include maximum operating temperature, pressure class, valve size, process media, body and disc materials, seat construction, allowable leakage rate and operating torque. Actuator mounting, shaft protection and thermal isolation should also be evaluated where necessary to protect temperature-sensitive components. For critical isolation applications, buyers should verify the required pressure-temperature ratings, leakage performance and applicable testing or fire-safe qualifications. Selecting the appropriate triple-offset design helps support dependable shut-off, reduced sealing-surface wear and reliable service under specified high-temperature operating conditions.
