Flanged Triple Offset Butterfly Valve

ALIS Valves offers Flanged Triple Offset Butterfly Valves for industrial applications requiring reliable flow isolation, tight shut-off and durable performance under demanding operating conditions. These valves feature a triple-offset disc and seat geometry designed to minimize friction between sealing surfaces during operation. The offset arrangement allows the disc to move away from the seat as the valve opens, helping reduce wear and support consistent sealing performance over repeated operating cycles. The flanged end connections provide a secure bolted connection to compatible pipeline flanges, making installation and maintenance more convenient in industrial piping systems. Depending on the specified design, these valves can incorporate metal-to-metal sealing, robust body construction and compatible manual, pneumatic or electric actuators to meet different operating requirements.

Flanged Triple Offset Butterfly Valves are used in oil and gas facilities, refineries, petrochemical plants, power generation units, chemical processing systems and other industrial installations requiring dependable pipeline isolation. Depending on the selected materials, pressure class and sealing arrangement, they can be specified for compatible liquids, gases and steam within the rated operating limits. Important selection factors include valve size, flange standard, pressure rating, operating temperature, process media, body and disc materials, seat construction, leakage requirements and operating torque. Actuator sizing and compatibility with the pipeline control system should also be considered when automated operation is required. For high-temperature or critical isolation applications, buyers should verify the valve’s applicable testing, fire-safe qualification and pressure-temperature ratings. Selecting the correct valve configuration helps support reliable shut-off, reduced sealing-surface wear and long-term performance in demanding industrial services.
