Frequently Ask Questions

What Is a Top Entry Trunnion Ball Valve?

It is a trunnion-mounted ball valve with access to its internal components from the top of the valve body, designed for reliable isolation in demanding pipeline applications.

Is It Suitable for Large-Diameter Pipelines?

Yes. The trunnion-mounted design is well suited for large-diameter and high-pressure pipeline applications where operating torque can be significant.

Who Is a Top Entry Trunnion Ball Valve Manufacturer in India?

Alis Valves manufactures and supplies Top Entry Trunnion Ball Valves for oil & gas, petrochemical, power, chemical, and high-pressure pipeline applications.

What Is the Advantage of Top Entry Construction?

Top-entry construction allows the valve internals to be accessed from the top, which can simplify inspection and maintenance compared with some side-entry designs.

What Is the Difference Between Top Entry and Side Entry Ball Valves?

A top-entry valve allows access to the ball and internal components from the top, while side-entry designs generally require access through the valve body from the side.
