The main difference between top entry ball valves and side entry ball valves is where the ball and internals can be serviced or replaced.
1. Top Insertion Ball Valve
Top entry valves allow access from the top without removing the valve from the pipeline.
In top entry ball valves, the ball and other internal components such as seats, seals, and stem are accessible and serviceable from the top of the valve body.
Suitable Applications for Top Entry Ball Valves:
The top entry design allows for easier access and repair of internal components, saving time and effort.
This is especially beneficial for larger size valves and applications with high pressure or high flow conditions.
2. Side entry ball valve
For maintenance or replacement, it may be necessary to remove the valve from the pipeline.
The ball and internal components of side entry ball valves enter from the side of the valve body.
Suitable Applications for Side Entry Valves:
Side-entry valves may require more maintenance access space than top-entry ball valves, and are generally suitable for smaller sized valves.
Side-mounted valves are typically used for applications with lower pressures and smaller pipe sizes.
Summarize
The main difference between top entry ball valves and side entry ball valves is the orientation of the ball and internals for maintenance or replacement.
The choice between the two types depends on factors such as valve size, pressure, flow conditions and maintenance requirements.
