Pneumatic Trunnion Ball Valve, API 6D, A216 WCB, DN500, PN40

Product Name: Pneumatic Actuated Trunnion Ball Valve
Type: Trunnion Mounted Ball Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: DN500, 20 Inch
Pressure: PN40, Class 300 LB
End Connection: RF
Operation: Pneumatic Actuator

Trunnion mounted ball valves are designed for easy and smooth operation under high line pressure. The ball is fixed in position, yet free to rotate, ensuring low torque operation with the assistance of carefully aligned bearings. These 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. KOSEN Cast Steel Trunnion Ball Valves are available in Two-Piece Split Body and Three-Piece Bolted Body configurations. They are designed and manufactured to the most current international standards, including API 6D, ASME B16.34, and BS 5351, or their equivalents. Standard features include fire safety, anti-static construction, and a blow-out proof stem.
