Top Entry Ball Valve

Our trunnion-mounted top-entry high-performance ball valves are designed to conform to a variety of standards, including API 6A, API 6D, ASME B16.34, and ISO 17292, among others. The range includes both soft, metal, and composite seats that can be designed with either a single or double piston effect in order to achieve a reliable double block and bleed (DB&B) in both the closed and, on request, the open position. This is possible because the seats can be constructed with either a single or double-piston effect.

The top entry ball valve is the valve that assembles the ball from the top end. It is also known as top entry gate valves. In the production of top-entry ball valves, Cast metal is often used. The structure of the body and cap of this one is similar to that of globe valves; however, there is a trim on this valve type.


  • Because of its top entrance and line maintenance characteristics, the TOP ENTRY BALL VALVE is often used in pipeline and industrial systems. 
  • It has numerous advantages including its low fluid resistance, straightforward construction, small volume, light weight, dependable salting, easy control, straightforward opening, and start/close versatility.
  • It differs most noticeably from the conventional ball valve in that it does not need removing the valve from the pipeline whenever routine maintenance is required. 
  • To prevent dirt and grime from settling into the rear of the seat, it has an adaptable design. 
  • The valve’s internal components have been carefully designed and selected to provide consistent performance under all operating circumstances.
  • It has simplified Valve maintenance, and pipe pressure is sustained, thanks to its adaptability to high-strength connective bolts.
