Many top entry ball valve manufacturers in the market offer top entry ball valves. But what are they? A top entry ball valve is similar to a globe valve that assembles the ball from the top end. Generally, the top entry ball valves are made up of cast metal. Therefore, certain additional NDE tests would be required to ensure that the ball is manufactured properly through casting. Dombor offers the best quality top entry ball valves. 

What are top entry ball valves?

Ball valves are generally used in oil & gas pipelines. These top entry ball valves are also used in oil, chemical, chemical, metallurgical, refining, petrochemical, electrical, nuclear, and paper machinery.


Due to different operating conditions and extreme environmental conditions, a typical ball valve is not enough, as the system demands high performance. With the help of the top entry structure, one can easily remove the ball valve from the valve line when replacing the seat. Also, it is easy to check and maintain the side entry ball valve.

Valve Body

The valve body is the core of the valve. It contains all the components for switching off or switching on the control.


The ball is designed with a center hole known as a bore, so the media flows through it. The direction of the ball can be controlled by turning the stem.


The stem is used for connecting the ball with the control mechanism.


Packing is a seal around the stem that prevents the media from escaping.


Bonnet is that body part that consists of the stem and packing.
