1. Double sealing design (bellows + packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards.
2. There is no fluid loss, reducing energy loss and improving plant equipment safety.
3. Long service life, reduce maintenance times and reduce operating costs.
4. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.
5. The gas medium valve seat adopts PTFE soft sealing material to improve the sealing performance of the valve.
6. The valve seat with high temperature resistance ≤425℃ adopts conical hard seal. Achieve zero leakage of air tightness.
