Choosing the right ball valve is crucial for ensuring the efficiency and longevity of your system. Top entry and side entry ball valves each have their own unique benefits. This guide will compare both types and help you determine which is best for your needs.
A top entry ball valve is a type of valve in which the body is accessed from the top for maintenance and installation. This design is often used in applications requiring frequent maintenance or in larger systems where ease of access is essential.
Ease of Maintenance: The top entry design allows for easier disassembly and maintenance.
Compact Design: Typically more compact and easier to install in systems with limited space.
Versatile Applications: Suitable for both high-pressure and large diameter systems.
Top entry ball valves comply with international standards such as API 6D and ISO 9001, ensuring they meet industry-specific performance and safety requirements.

A side entry ball valve, on the other hand, is designed with the valve body accessed from the side. This design is often used in applications where space or specific design requirements do not allow for a top entry configuration.
Cost-Effective: Side entry valves are often more affordable compared to top entry valves due to their simpler construction.
Suitable for Larger Systems: Ideal for applications where top access is not possible.
More Complex Maintenance: Requires more effort for disassembly and maintenance compared to top entry valves.
Top Entry Design: The ball valve is accessed from the top for maintenance, making it ideal for systems where ease of access is important. The ball inside the valve rotates to regulate the flow of the medium, and the design allows for in-line maintenance without removing the valve from the pipeline.
Side Entry Design: The valve body is accessed from the side, making it ideal for applications with space constraints. The working principle is similar, with the ball inside the valve rotating to control the flow. However, maintenance is more difficult as the valve has to be removed from the pipeline for disassembly.
Easier Maintenance: With top access, maintenance and repairs are more straightforward.
Compact and Space-Saving: Ideal for systems with limited space.
Higher Pressure Ratings: Often used in high-pressure systems.
Cost: Typically more expensive due to the complex design.
Limited Availability: May not be available in all sizes or configurations.
Cost-Effective: More affordable and simpler to manufacture.
Ideal for Large Systems: Can be used in systems where top entry is not feasible.
Difficult Maintenance: Requires disassembly from the pipeline for maintenance.
Larger Footprint: May require more space compared to top entry valves.
High-Pressure Systems: These valves are ideal for applications where high pressure is required.
Oil & Gas: Used in pipeline systems for oil and gas transportation, where frequent maintenance is needed.
District Heating: Suitable for heating systems with large pipes.
Large-Diameter Pipelines: Often used in large-diameter systems where top access is impractical.
Water Treatment Plants: Common in water and wastewater treatment systems.
Chemical Processing: Ideal for systems that require regular but less complex maintenance.
When deciding between top entry and side entry ball valves, consider these factors:
Space Availability: If you have limited space, side entry may be the better choice.
Maintenance Frequency: For systems that require regular maintenance, a top entry ball valve may be more efficient.
Pressure and Size Requirements: Top entry ball valves are better suited for high-pressure applications, while side entry valves can handle larger systems with lower maintenance needs.
Q: Which is better for high-pressure systems, top entry or side entry?
Top entry ball valves are typically better suited for high-pressure systems due to their stronger construction and easier maintenance.
Q: Can side entry ball valves be used in confined spaces?
Yes, side entry ball valves are often used in applications where top entry is not possible, making them ideal for confined spaces.
Q: Are top entry ball valves more expensive than side entry?
Yes, top entry valves tend to be more expensive due to their complex design and ease of maintenance.
The choice between top entry and side entry ball valves depends on your system’s requirements. Top entry valves are ideal for high-pressure systems and easy maintenance, while side entry valves offer a more cost-effective solution for larger systems.
