1. During the opening and closing process, because the friction between the valve disc and the valve body sealing surface is smaller than that of the gate valve, it is wear-resistant.
2. The opening height is generally only 1/4 of the valve seat channel, so it is much smaller than the gate valve;
3. Usually there is only one sealing surface on the valve body and valve disc, so the manufacturing process is relatively good and easy to maintain.
4. Since its filler is generally a mixture of asbestos and graphite, it has a higher temperature resistance level. Generally, stop valves are used for steam valves.
5. Double sealing design (bellows + packing) If the bellows fails, the valve stem packing will also be avoided;
6. External leakage, and complies with international sealing standards;
7. There is no fluid loss, reducing energy loss and improving factory equipment safety;
8. Long service life, reducing maintenance times and operating costs;
9. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.
10. The bellows seal globe valve adopts the bellows seal design, which completely eliminates the shortcomings of ordinary valve stem packing seals that age quickly and leak easily. It not only improves energy efficiency, increases the safety of production equipment, but also reduces maintenance costs and frequent inspections. Maintenance and maintenance also provide a clean and safe working environment.
