1. Main structural features
1. Fixed ball design
● Double support upper and lower shaft design (70% reduction in operating torque)
● Tungsten carbide (HVOF) coating on the ball surface (hardness ≥HRC72)
● BOP stem design (API 6D standard)
2. Sealing system
● Double piston valve seat (bi-directional seal)
● Metal solid seal (temperature resistance up to 650°C)
● Fireproof design (API 607 certification)
3. Drive Mode
● Worm Drive (Standard Configuration)
● Electric/pneumatic actuator (optional)
● Reducer Reducer (DN600 and above)
2. Performance Benefits
1. Design Advantages
● 50% increased load capacity (compared with floating ball valve)
● Flow resistance coefficient ≤0.03 (full bore design)
● Seismic performance meets IEEE 693 standard
2. Sealing characteristics
● Two-way zero leakage (API Class 6D A)
● Automatic pressure compensation function
● Leak-proof after fire protection (30 minutes)
3. Service Benefits
● Online maintenance design (no need to disassemble the valve body)
● Valve seat can be replaced separately
● Maintenance-free period ≥ 10 years
