The thermal insulation performance of valves has an important impact on the normal operation of the whole pipeline and the exertion of economic benefits. What is the impact of thermal insulation pneumatic ball valves on the operation of equipment? This paper analyzes the specific impact from four aspects: the impact of thermal alternation, the impact of corrosion on exposed valves, the impact of thermal expansion difference, and the impact of thermal expansion difference between flanges and bolts.

Classification of pneumatic ball valves:
Pneumatic steam ball valve: the pneumatic steam ball valve is composed of a pneumatic actuator and a precision casting high platform ball valve. With purified dry compressed air as the power source, it receives air signals or electrical valve locators, solenoid valves and other accessories, and receives electrical signals to work. It has the characteristics of compact overall structure, quick opening and closing, simple operation and good reliability.
