ASTM A351 CF8 Trunnion Ball Valve, API 6D, 8 IN, 600 LB, RF

Product Name: Stainless Steel Trunnion Ball Valve
Design Standard: API 6D
Body Material: ASTM A351 CF8
Size: 8 Inch, DN200
Pressure: Class 600 LB, PN100
End Connection: RF
Operation: Gearbox

Trunnion Mounted Ball Valves are designed for smooth and efficient operation under high line pressure. These valves feature carefully aligned bearings that ensure low torque operation. The ball is fixed in position but remains free to rotate, providing reliable performance. All Cast Trunnion Ball Valves are constructed with high-quality castings and are fire-safe, meeting certifications such as BS 6755, API 607, and API 6FA, along with all applicable ASME standards. Available in Two-Piece Split Body and Three-Piece Bolted Body configurations, these valves are engineered to meet the latest international standards, including API 6D, ASME B16.34, and BS 5351. Key features include Fire Safe, Anti-static, and Blow-out Proof Stem designs.
