Product Description

1. Double seal design (bellows + packing) If bellows fail, stem packing will also avoid leakage and conform to international sealing standards.

2. no fluid loss, reduce energy loss and improve plant safety.

3. long service life, fewer maintenance times and lower operating costs.

4. rugged bellows seal design ensures zero leakage of stem and provides no maintenance conditions.

5. gas medium valve seat adopts PTFE soft sealing material to improve the sealing performance of the valve.

6. high temperature resistant or less than 425 degree valve seat adopts cone hard seal. Air tight performance zero leakage
