Double Eccentric Flanged Butterfly Valves – Industrial-Grade Sealing Solutions
Superior Design for Demanding Applications
Our double eccentric butterfly valves utilize a patented dual-offset cam mechanism to eliminate friction during operation, reducing torque by 40% and extending service life by up to 30% compared to conventional valves. The spindle’s unique dual-offset geometry enables.
✅ Zero leakage (bidirectional bubble-tight sealing per API 598)
✅ Low-maintenance operation with replaceable lip-seat technology
✅ Wide temperature range (-196°C to +815°C / -320°F to +1500°F)
✅ Blowout-proof stem with split collar safety design
