Characteristics of Different Valves (3)

Through the analysis of six common valve types in chemical pipeline design, we gain insights into their unique characteristics—knowledge that informs rational valve selection. Key takeaways for practical applications include:

• High-temperature Steam & Oil-Gas Media: Opt for wedge-type single-disc gate valves, which excel in high-temperature and high-pressure environments.
• Pure Media Transportation: Check valves are ideal for preventing backflow in clean fluid systems.
• Butterfly Valves: Restrict use to low-temperature and low-pressure conditions to maintain sealing integrity.
• Ball Valves: Suit best for transporting low-temperature, high-pressure, or viscous fluids in systems requiring tight sealing.

Conclusion

Valve selection is pivotal in chemical pipeline design, directly impacting operational safety and efficiency. To ensure optimal performance, engineers must:

1. Deeply understand each valve’s technical specifications (e.g., pressure rating, temperature tolerance, flow characteristics).
2. Align selections with process requirements, such as medium corrosiveness, flow rate, and system pressure.

This paper analyzed the characteristics of gate valves, globe valves, check valves, butterfly valves, plug valves, ball valves, and diaphragm valves—highlighting their application scenarios. It is recommended that designers integrate multi-factor considerations (e.g., cost, maintenance, safety) to enhance chemical production reliability and efficiency.
