Wafer Type Triple Offset Butterfly Valve

ALIS Valves offers Wafer Type Triple Offset Butterfly Valves for industrial applications requiring reliable flow isolation, tight shut-off and efficient installation within pipeline systems. These valves feature a triple-offset disc and seat geometry designed to minimize friction between sealing surfaces during opening and closing. The offset arrangement allows the disc to disengage from the seat as the valve opens, helping reduce wear and support consistent sealing performance over repeated operating cycles. The wafer-style body is designed to fit between compatible pipeline flanges and is secured using the specified bolting arrangement, providing a compact solution for installations where space and weight are important considerations. Depending on the valve design, these valves can incorporate metal-to-metal sealing, robust body materials and compatible manual, pneumatic or electric actuators for reliable operation under specified process conditions.

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