What Are the Common Misconceptions About Ball Valves?

Demystifying common misconceptions about ball valves

I would like to discuss common misunderstandings about ball valves with you, and correct these misunderstandings through in-depth analysis and professional knowledge to improve the correct understanding and application of ball valves. In fluid control systems, ball valves are widely used because of their high efficiency and reliability. However, various misunderstandings about ball valves also affect the decisions of engineers and purchasers, ball valve factory.

1. Misunderstandings about the structure of ball valves

Ball valve has only one sealing surface
Fact: Ball valves have two sealing surfaces, one between the ball and the seat. This construction gives the ball valve excellent performance in bi-directional flow applications, gate valve factory.

The ball material is usually plastic
Fact: While some ball valves do use plastic balls, most high-performance ball valves have metal balls such as stainless steel, carbon steel, and titanium alloys. These materials provide ball valves with better strength and corrosion resistance.

2. Misunderstandings about ball valve performance

Ball valves are not suitable for high pressure applications
Fact: Ball valves are specially designed and manufactured to withstand pressures up to thousands of pounds. For example, a ball valve with full metal seal has a pressure rating of up to Class 6000.

Ball valves have lower leakage levels
Fact: In fact, many high-performance ball valves meet strict leakage standards such as ANSI/FCI 70-2 or ISO 15848. These standards ensure a low leakage rate of ball valves in the closed state.

3. Misunderstandings about ball valve selection and installation

All ball valves are suitable for all fluid media
Fact: Different fluid media have different requirements for ball valve materials and structures. For example, corrosive media requires the use of balls and valve seats made of corrosion-resistant materials; high-viscosity media may require the use of V-shaped ball valves to achieve better flow regulation, bronze valve factory.

No special precautions are required for ball valve installation
Fact: Proper installation is critical to ensuring ball valve performance and longevity. During installation, avoid over-tightening the bolts to avoid damage between the ball and the valve seat; at the same time, ensure that the direction of the fluid is consistent with the flow arrow on the ball to prevent leakage and damage.

4. Misunderstandings about ball valve maintenance and repair

Ball valves require no regular maintenance
Fact: Regular maintenance is essential to maintain ball valve performance and extend service life. Maintenance work includes lubrication of operating mechanisms, inspection of seals and replacement of damaged parts. Through regular maintenance, you can ensure that the ball valve can close quickly in an emergency and reduce the risk of leakage, check valve factory.

Ball valve maintenance is difficult and costly
Fact: Service on ball valves is relatively simple and affordable compared to other valves. Many ball valves feature a modular design, making component replacement easy and convenient. In addition, due to the simple structure of ball valves, relatively few professional skills and tools are required for repair.

Through an in-depth analysis of common misunderstandings about ball valves, it aims to improve the correct understanding and application of ball valves by engineers and purchasers. By eliminating these misunderstandings, we can better select, install and maintain ball valves to ensure safe and efficient operation of fluid control systems. At the same time, we also hope that this article can inspire more professionals to discuss and research interest in ball valve technology, and jointly promote the progress and development of fluid control technology.
