1. Top-loading design: The valve body is opened from the top, which is convenient for online repair and maintenance without disassembling the pipeline.
2. Easy maintenance: The replacement and repair of the internal components of the valve are simplified, reducing downtime.
3. Integral structure: The integral forged valve body is usually adopted, which increases the strength and durability of the valve.
4. Tight closing: The ball design ensures tight closing to prevent leakage, suitable for high pressure and high temperature conditions.
5. Low torque operation: The design is optimized to reduce the torque required during operation and improve operating efficiency.
6. Corrosion-resistant materials: The valve body and ball are usually made of corrosion-resistant materials such as stainless steel or alloy steel, which are suitable for corrosive media.
7. Applicable to a variety of media: It is widely used in oil and gas, chemical, petrochemical, marine engineering and other fields, with strong adaptability.
8. Strong erosion resistance: It has good erosion resistance and is suitable for working conditions with particle-containing media or high flow rates.
9. High reliability: The solid structure and high-quality sealing materials ensure the long-term stable operation of the valve.
Top Entry Ball Valve, also called as Top Mounted Ball Valve, is designed to provide easy access to the valve internals for maintenance and repair without having to remove the valve from the pipeline. This can save a lot of time and effort during maintenance and help to reduce downtime.
Additionally, the top entry design allows for the use of larger diameter balls, which can help to reduce the operating torque required to open and close the valve. This can result in lower operating costs and longer service life for the valve.
Top Entry Ball Valve is commonly used in the oil and gas industry, where reliability and ease of maintenance are critical factors.

Structure Features
Integral Valve Body Design
Features a top-mounted trunnion fixed support flange or butt welding structure.
Inconel Corrugated Spring
Allows the sealed metal valve seat to move to the ball, providing two-way sealing of the inlet and outlet.
Unique Valve Seat Retractable Technology
Allows for online replacement of the ball rod, resulting in a longer service life for the metal valve stem seal ring and corrugation, and reduced torque for easy valve operation.
Easy to Maintain, Install, Has a Long Service Life
The valve does not need to be removed from the pipeline for internal parts repair or replacement.
Small Torque and Reliable Sealing
The spherical structure of our valve seat is different from that of ordinary ball valves, allowing for automatic adjustment of the sealing position.
Features a Drive Device Platform and Screw Holes
Meet the requirements of ISO 5211. The drive device can be assembled at any time according to the different requirements of users.
DBB Design
Double blocking and venting, provide an extra level of safety and protection against leaks, particularly in critical applications such as in the oil and gas industry.
High-Strength Integral Ball Rod Structure
Ensure precise positioning of the ball.
Anti-Blowout Protection Structure
Improve the safety of valve operation.
