Cast Floating Ball Valves are designed with the ball supported by two PTFE seats, one on the upstream side and the other on the downstream side. Under upstream pressure, the ball is pushed toward the downstream seat, compressing it to achieve a complete shutoff and ensure reliable fluid control. All Cast Floating Ball Valves are produced with high-quality castings and feature a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA. They comply fully with all applicable ASME standards. Floating Ball Valves are available in One-Piece Uni-body, Two-Piece Split Body, and Three-Piece Bolted Body configurations. They are designed and manufactured to the latest international standards such as API 6D, ASME B16.34, BS 5351, or their equivalents. Standard features include fire-safe construction, anti-static protection, and a blowout-proof stem.
