Product Name: Cast Trunnion Mounted Ball Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: 8 Inch, DN200
Pressure: Class 900 LB, PN150
End Connection: RTJ Flanged
Operation: Gearbox
Trunnion Mounted Ball Valves are designed for easy and smooth operation under high line pressure. Aligned bearings ensure low-torque operation, while the ball remains fixed in position but is free to rotate. All Cast Trunnion Ball Valves are made with high-quality castings and feature a fire-safe design, certified according to BS 6755, API 607, and API 6FA, while meeting all applicable ASME standards. These valves are available in Two-Piece Split Body and Three-Piece Bolted Body configurations. Designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351 or equivalent, they come with standard features such as Fire Safe, Anti-static, and Stem Blow-out Proof protection.
