The cast floating ball valve design supports the ball with two PTFE seats，one on the upstream side and one on the downstream side. When upstream pressure acts on the ball, it pushes the ball against the downstream seat, creating a tight and reliable shutoff for fluid control. All cast floating ball valves manufactured by KOSEN feature high-quality, reliable castings and fire-safe designs certified to BS 6755, API 607, and API 6FA. They meet all applicable ASME standards. Floating ball valves are available in one-piece unibody, two-piece split-body, and three-piece bolted-body configurations. They are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalent specifications. Standard features include fire-safe construction, anti-static design, and a blowout-proof stem.
