Alis Valves offers Floating Top Entry Ball Valve Manufacturer Supplier in India designed for reliable isolation and efficient flow control in industrial piping systems. The floating ball is not fixed to the stem and moves slightly under line pressure, pressing against the downstream seat to provide effective sealing. The top-entry construction allows inspection and maintenance of internal components from the top of the valve, reducing maintenance time and simplifying servicing without complete valve removal from the pipeline.

Frequently Ask Questions
A Floating Top Entry Ball Valve is a quarter-turn ball valve that uses a floating ball for sealing and has a top-entry body design, allowing access to the internal components from the top.
Top entry means the valve's internal components can be accessed by removing the bonnet or top cover from above rather than removing the entire valve from the pipeline.
A Top Entry Ball Valve provides access to internal components from the top.
A Side Entry Ball Valve is assembled through the side of the body, often using a multi-piece construction.
Top-entry designs can be advantageous where in-line maintenance and reduced pipeline disturbance are important.
Alis Valves is a Floating Top Entry Ball Valve manufacturer and supplier in India, offering ball valve solutions for oil & gas, refinery, petrochemical, chemical, power and industrial process applications.
The ball is not rigidly fixed to a stem at both ends. When the valve is closed, line pressure pushes the ball toward the downstream seat, helping create a tight seal.
The main advantage is easier access for inspection and maintenance in suitable installations. In some applications, this can reduce the need to remove the complete valve from the pipeline.
It can be used for suitable pressure ranges, but floating ball valves are generally selected according to size and pressure requirements. For very large sizes or severe high-pressure service, a trunnion-mounted ball valve may be more appropriate.
