Floating Top Entry Ball Valve

ALIS Valves offers Floating Top Entry Ball Valves for industrial applications requiring reliable shut-off, effective sealing and convenient maintenance. These valves combine a floating ball design with a top-entry body configuration. The ball is not rigidly fixed and moves slightly under fluid pressure to press against the downstream seat, helping provide a tight seal when the valve is closed. The top-entry construction allows access to internal components, such as the ball and seats, from the top of the valve, simplifying inspection and maintenance without requiring complete removal of the valve body from the pipeline.

Floating Top Entry Ball Valves are suitable for compatible applications in oil and gas facilities, chemical processing plants, refineries, petrochemical industries and general industrial pipeline systems. They are commonly selected for low- to medium-pressure services, depending on the valve design, size and pressure rating. Important selection factors include operating pressure, temperature, process media, valve size, body and seat materials, end connections and applicable industry standards. Choosing the appropriate valve configuration helps support dependable shut-off, easier maintenance access and reliable performance under the specified operating conditions.
