Product Name: Stainless Steel Cryogenic Ball Valve
Type: Trunnion Mounted Ball Valve
Design Standard: API 6D
Body Material: ASTM A182 F304, Stainless Steel
Size: Custom
Pressure: Class 150 LB, PN20
End Connection: RF Flanged
Operation: Gear
Trunnion-mounted ball valves provide smooth and easy operation even at high line pressures. Carefully aligned bearings reduce operating torque, while the ball remains fixed in position yet free to rotate. All cast trunnion ball valves feature high-quality, reliable castings and a fire-safe design certified according to BS 6755, API 607, and API 6FA, meeting all applicable ASME standards. Cast steel trunnion ball valves are available in two-piece split-body and three-piece bolted-body designs. They are engineered and manufactured to the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalent standards, and come with standard features such as fire-safe construction, anti-static design, and stem blowout-proof protection.
