AJ Series 985
Triple Eccentric Butterfly Valve
Triple-eccentric, metal-seated butterfly valve for excellent performance in many applications. Available as Flanged short pattern, Flanged long pattern, Wafer, Lug, and Buttwelded ends. The valves can be supplied with different body, disc, and seal materials to meet specific application requirements and ensure optimal performance.
Engineered with an advanced triple-eccentric geometry, the valve ensures precise, low-torque operation even in demanding applications. The metal-to-metal sealing system provides reliable tightness with minimal wear, offering exceptional durability throughout the valve’ service life. High-grade materials ensure long-term performance in harsh environments. The valves are designed for true zero-leakage capability and are suitable for bi-directional isolation and control in high-temperature and high-pressure conditions.
