The Cast Floating Ball Valve features a design where the ball is supported by two PTFE seats, one on the upstream and the other on the downstream side of the ball. The upstream pressure pushes the ball, compressing the downstream seat to provide a complete shutoff, effectively controlling fluid flow.
KOSEN's Cast Floating Ball Valves are manufactured using high-quality castings, ensuring reliability and durability. These valves are designed with a fire-safe feature and are certified to meet industry standards such as BS 6755, API 607, and API 6FA, as well as all relevant ASME standards.
Available in three configurations, One-Piece Uni-Body, Two-Piece Split Body, and Three-Piece Bolted Body, these valves are built to the most updated international standards, including API 6D, ASME B16.34, and BS 5351 (or equivalent). Standard features of Floating Ball Valves include fire safety, anti-static properties, and blow-out protection, ensuring robust performance and safety in demanding applications.
