1. Double seal Design (bellows + filler) If bellows failure, stem filler will also be avoided;
2. External leakage and conform to international sealing standards;
3. No fluid loss, reduce energy loss, improve plant equipment safety;
4. Long service life, reduce maintenance times, reduce operating costs;
5. Rugged Bellows seal design ensures 0 leakage of stem and provides no maintenance conditions.
6. Bellows sealed cut-off valve with bellows seal design, completely eliminates the common valve stem packing seal aging fast and easy to leak the shortcomings, not only improve the use of energy efficiency, increase production equipment safety, reduce maintenance costs and frequent maintenance, but also provide a clean and safe working environment.
