1. The Valve Body are forged.
2. The Patented stem sealing technology (Double Wedged Self Tight Sealing Structure) is adopted for this valve to reduce the pressure of stem sealing packings, and make sure upper sealing is more effective and reliable.
3. The surface of the valve element and seat is STL overlaying.
4. Live loading structure is used for the packing gland.
5. The nonrotating stem design is adopted.
6. Combined stem packing structure which is used for the high pressure and temperature specially is adopted to make the valve meet the no leakage request.
