Fire Safe Triple Offset Butterfly Valve

ALIS Valves offers Fire Safe Triple Offset Butterfly Valves for industrial applications requiring reliable flow isolation, tight shut-off and enhanced performance under high-temperature and fire-exposure conditions. These valves feature a triple-offset disc and seat geometry designed to minimize friction during operation and provide a cam-like movement that helps the disc disengage from the seat as the valve opens. This design supports metal-to-metal sealing in suitable configurations and reduces seat wear during repeated operating cycles. Fire-safe construction is intended to help maintain an acceptable level of sealing performance during and after exposure to fire, subject to the valve’s design and applicable fire-testing standards. Depending on the application, these valves can be supplied with suitable body materials, high-temperature sealing components and compatible manual, pneumatic or electric actuation systems.

Fire Safe Triple Offset Butterfly Valves are used in oil and gas facilities, refineries, petrochemical plants, power generation units, fuel handling systems and other industrial installations where fire safety and dependable isolation are important. They can be selected for compatible liquids, gases and steam within the specified pressure and temperature ratings. Important selection factors include valve size, pressure class, operating temperature, process media, body and disc materials, seat and seal construction, operating torque, actuator requirements and applicable fire-safe certification. Buyers should verify compliance with the required fire-testing standard, such as API 607 or API 6FA where applicable, along with the required leakage performance and pressure rating. Selecting a properly rated and tested valve helps support dependable isolation, reduced operating friction and improved safety in demanding process environments.
