Top Entry Ball 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.

STRUCTURAL FEATURES

1. Integral Valve Body Design

Features a top-mounted trunnion fixed support flange or butt welding structure.

2. Inconel Corrugated Spring

Allows the sealed metal valve seat to move to the ball, providing two-way sealing of the inlet and outlet.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. High-Strength Integral Ball Rod Structure

Ensure precise positioning of the ball.

9. Anti-Blowout Protection Structure

Improve the safety of valve operation.

Our top entry ball valve is a newly developed product that integrates our company’s years of design and manufacturing experience with advanced foreign technology. The technical level of our valve has reached the domestic first-class level, and our product is comparable to international counterparts.
