Cast Steel Trunnion Ball Valve, API 6D, WCB, DN500, PN40, RF

Product Name: Cast Steel Trunnion Ball Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: DN500, 20 Inch
Pressure: PN40, Class 300 LB
End Connection: RF
Operation: Worm Gear

Trunnion Mounted Ball Valves are designed for easy and smooth operation at high line pressures. The carefully aligned bearings ensure low-torque operation, while the ball is fixed in position but free to rotate. All Cast Trunnion Ball Valves are built with reliable, high-quality castings and feature a fire-safe design, certified according to BS 6755, API 607, and API 6FA. These valves meet all applicable ASME standards. Available in Two-Piece Split Body and Three-Piece Bolted Body configurations, KOSEN's Cast Steel Trunnion Ball Valves are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, BS 5351, or their equivalents. Standard features include fire safety, anti-static protection, and blow-out proof stem design.
