Valves Only, one of the prominent Top Entry [Ball Valve Suppliers](https://valvesonly.com/product-category/top-entry-ball-valve/) in USA, provides high quality top entry ball valves for different industrial uses. Top entry ball valves are employed in high pressure and high temperature uses, which are highly efficient and long-lasting valve designs.  As the valves are specially designed, they can be easily repaired and maintained without having to remove them from the pipeline. 

**What is a Ball Valve?** 

A ball valve is a quarter-turn valve utilized for controlling liquid or gas flow by an empty rotating ball.  When the pipe hole of the ball is placed on the same axis as the pipeline, it is open; when the valve is rotated 90 degrees, the flow will be completely obstructed. 

**Why is a Top Entry Ball Valve needed?** 

Where in-line serviceability is of concern, top entrance ball valves are necessary. They are the best suited to the following applications where the valve must not shift while under inspection or maintenance: 

•High-pressure systems 

•Audits requiring shut-down 

•Large pipe diameters 

**KeyParts of Top Entry Ball Valve:** 

1.Valve Body: The valve body is generally cast as one piece, providing top access. 

2.Ball: Solid or hollow, depending on the application. 

3\. Stem: Secures the ball against the actuator or handle. 

4\. Seats: Close the ball securely in a tight fit. 

5\. Bonnet: Provides access to the top entry and retains the stem. 

6\. Actuator: The valve position is controlled by the handle or actuator. 

**Working Mechanism:** 

The stem and ball are turned by the handle or actuator. Hollow ball allows fluid to flow through in the open state. Seating the solid component of the ball against the flow by a 90-degree turn closes the valve. Top entry design enables the technicians to fix internal components from the top side without unbolted the valve from the line. 

**Advantages of Using a Top Entry Ball Valve:** 

•Easy In-line Maintenance 

•Space-saving and Compact Design 

•High Temperature and Pressure Tolerance 

•Excellent Sealing Performance 

•Long Term Cost Savings 

**Functions:** 

1.On/off control of fluid system 

2.Pipeline section isolation
