1. -ISO5211 top flange design
2. In addition to the wear-resistant standard V-ring packing, graphite high-temperature packing or low-leakage packing can also be selected
3. Bidirectional sealing performance
4. Optional rubber, PTFE,RPTFE, and fire-resistant PTFE valve seats are available
5. Negligible valve seat wear and low operating torque ensure a long service life of the valve seat
6. Active mechanical seals no longer rely on pipeline pressure
