Learn the ball valve sealing principle and key differences between soft seal and hard seal ball valves. Compare applicable media, temperature resistance, wear performance, and how to select the right valve based on working conditions – clean media, high temperature, particles, or high pressure. Industrial valve selection guide.

Discover how power station valves achieve zero leakage through three safety barriers: valve seat sealing, stem sealing, and body-bonnet joint design. Learn about redundant sealing structures for high-temperature, high-pressure power plant applications.

This article analyzes common causes of valve sealing surface failure under high temperature and high pressure conditions, and provides three major solutions from material selection, structural design and manufacturing process to improve valve sealing reliability and prevent leakage.

This guide covers ball valve application scenarios, scientific selection methods, and key maintenance points, helping you choose and maintain ball valves for various working conditions.

Explore the key advantages and disadvantages of ball valves, including simple structure, rapid operation, excellent sealing, and limitations in flow regulation and high-temperature applications.
