Cast Floating Ball Valves are engineered with a floating ball design supported by two PTFE seats, positioned on the upstream and downstream sides. Line pressure from the upstream side pushes the ball against the downstream seat, ensuring a secure and reliable shutoff. Manufactured using high-quality castings, these valves comply with international fire-safe standards such as BS 6755, API 607, and API 6FA, and meet all applicable ASME standards. Cast Floating Ball Valves are available in One-Piece Uni-body, Two-Piece Split Body, and Three-Piece Bolted Body configurations. They are designed and produced according to updated global standards including API 6D, ASME B16.34, and BS 5351. Standard features include fire-safe design, anti-static construction, and blow-out-proof stems, ensuring safe and dependable operation in a wide range of industrial applications.
