What are the advantages of bellows globe valves compared to ordinary globe valves? Valves are an essential part of many pipelines, and the quality of the valve affects the performance of pipeline transportation. Besides high sealing requirements, valves also demand high operational flexibility. Therefore, many valves have undergone continuous technological improvements and upgrades, with old and outdated valves gradually being replaced by better designs. Bellows globe valves are considered a better design compared to ordinary globe valves. So, what are the differences between bellows globe valves and ordinary globe valves? What are the advantages of bellows globe valves? Here, the editor introduces them to you.

Valves are an essential part of many pipelines. The quality of the valve affects the performance of pipeline transportation. Besides high sealing requirements, valves also demand high operational flexibility. Therefore, many valves are continuously improved and upgraded technologically, with old and outdated valves gradually being replaced by better designs. Bellows Globe Valve Compared to ordinary globe valves, it is a better design, so, Bellows Globe Valve What are the differences compared to ordinary globe valves? What are the advantages of bellows globe valves? Let me introduce them to you now.
Bellows Globe Valve Comparison with ordinary globe valves
1. Bellows Globe Valve No leakage, suitable for hazardous media, safe and reliable.
2. Ordinary globe valves use packing seals; the valve stem and packing slide, which can easily leak at low temperatures (valve core).
3 . Bellows Globe Valve Bellows made of stretch and compression can replace packing seals, effectively preventing losses caused by packing leakage. Generally used for transporting permeable media, such as valves in hydrogen systems, which usually have no leakage as long as the bellows are intact; ordinary globe valves use packing seals and are prone to leakage.
4. This type of valve stem has a relatively short opening and closing stroke and a very reliable shut-off function. Due to changes in the valve seat, the valve disc stroke changes proportionally, making it very suitable for flow regulation. Therefore, this type of valve is very suitable for shut-off, regulation, and throttling.
Advantages of Bellows Globe Valves
1. Double sealing design (bellows + packing). If the bellows fail, the valve stem packing also prevents leakage and meets international sealing standards.
2. No fluid loss, reducing energy loss and improving plant equipment safety.
3. Long service life, reducing maintenance frequency and lowering operating costs.
4. Durable bellows seal design ensures zero leakage of the valve stem with no maintenance required.
5. The valve seat for gas media uses PTFE soft sealing material, enhancing the valve's sealing performance.
6. High temperature resistance ≤425℃. The valve seat uses a conical hard seal, achieving airtight performance and zero leakage.
With rising labor costs, reducing manual labor is increasingly desired by many companies. Such bellows globe valves make it easier for workers to operate the product, have a longer service life, and better sealing performance. It is reasonable to believe their prospects will become broader.
Above is a brief introduction to the differences between bellows globe valves and ordinary globe valves and the advantages of bellows globe valves. We can see that many product or tool updates are not only improvements and breakthroughs in key technologies but also updates in design details. Therefore, bellows globe valves have many advantages over ordinary globe valves. If consumers want to purchase valves, it is recommended to buy bellows globe valves.
