Differences between Lined Globe Valves and Ordinary Globe Valves

Lined globe valves and ordinary globe valves have some significant differences in their structure and usage characteristics.

The following are their main differences:

1. Structure

Lined globe valve: This valve is lined with a corrosion-resistant material, such as rubber or plastic, to enhance its corrosion resistance. The choice of lining material depends on the nature of the media and the operating environment.

Ordinary globe valve: Made of traditional metal materials and without a special lining. Its sealing is primarily achieved through the packing seal structure, which compresses the packing.

2. Usage Characteristics

Lined globe valve:

Corrosion resistance: Due to the corrosion-resistant material lining, lined globe valves are suitable for piping systems with corrosive media, effectively preventing corrosion from the media.

Scope of application: Suitable for piping systems with corrosive media in the chemical, pharmaceutical, and food industries.

Sealing performance: The lining material provides excellent sealing performance, reducing the possibility of leakage.

Ordinary globe valve:

Scope of application: Suitable for general industrial pipelines, such as those with non-corrosive media such as water, steam, and oil. Sealing Performance: While they offer good sealing performance, their service life is relatively short under high temperatures, high pressures, and corrosive media.

Cost: They are relatively inexpensive and have a wide range of applications.

3. Price and Application

Lined Globe Valves: Due to the addition of lining material, the manufacturing cost is relatively high, resulting in a higher price. They are suitable for special applications requiring corrosion resistance.

Ordinary Globe Valves: They have lower manufacturing costs and are relatively affordable, making them suitable for general industrial piping systems.

4. Maintenance and Care

Lined Globe Valves: Due to the presence of the lining material, special attention must be paid to the integrity of the lining during maintenance to prevent corrosion caused by lining damage.

Ordinary Globe Valves: Maintenance is relatively simple, primarily requiring inspection of the packing seal and regular replacement of the packing.

Summary

The main differences between lined and ordinary globe valves lie in their structure and usage characteristics. Lined globe valves, enhanced by internal lining material, offer enhanced corrosion resistance and are suitable for piping systems handling corrosive media, while ordinary globe valves are suitable for general industrial piping systems. Lined globe valves are more expensive, but offer better sealing performance and a longer service life. Ordinary stop valves are relatively cheap and have a wide range of applications, but their service life is relatively short under special media.
