Causes and Measures for Bellows Sealed Globe Valve Failure

The bellows sealed globe valve, a modern variant of the traditional globe valve, utilizes a unique bellows sealing design. This design, with its dual sealing structure comprising both the bellows and packing, offers superior sealing performance compared to conventional globe valves. Bellows sealed globe valves are widely used in applications where high sealing reliability is critical, particularly in high-pressure, high-temperature environments like petrochemical, chemical, and steam systems. However,...

Valve Sealing Performance in Low-Temperature Conditions

The sealing performance of an industrial valve is one of the key indicators used to evaluate its quality. It primarily involves internal and external sealing performance. Sealing performance directly impacts the valve's operational efficiency and service life, particularly under harsh conditions such as high pressure, low temperatures, and corrosive media. Therefore, understanding the characteristics of different valve sealing elements, the selection of materials, and their applicable ranges...

Quick Shut-Off Ball Valves in Industrial Control Systems

In industrial control systems, quick shut-off ball valves play a critical role as key safety components. Their primary function is to rapidly shut off fluid flow in emergency situations, ensuring the safe operation of the system. In high-risk industries such as high-pressure gas, coal chemical processing, and petrochemical sectors, these valves are essential for quickly cutting off flammable, explosive, or toxic substances, preventing the escalation of accidents and further harm. Due to their simple...
