Low Temperature Ball Valve, API 6D, ASTM A182 F304, 6 Inches

Product Name: Low Temperature Ball Valve, Cryogenic Ball Valve
Type: Trunnion Mounted Ball Valve
Design Standard: API 6D
Body Material: ASTM A182 F304
Size: 6 Inch, DN150, 150 mm
Pressure: Class 150 LB, PN20
End Connection: Flanged
Operation: Gear

Trunnion-mounted ball valves enable easy, smooth operation even under high line pressure. Precisely aligned bearings support low-torque rotation, while the ball remains fixed in position but free to turn. All cast trunnion ball valves feature high-quality castings and a fire-safe design certified according to BS 6755, API 607, and API 6FA. They meet 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 their equivalents, and come with standard features such as fire-safe construction, anti-static design, and stem blowout-proof protection.
