Advantage
1.The valve body adopts German coated sand manufacturing technology, which is more advanced, filling up the disadvantages of easy leakage and high pollution of the traditional casting process, ensuring the valve zero leakage.
2.The valve disc adopts a tapered design. The sealing surface and the medium are streamlined, with better sealing performance and longer service life.
3.Treated by quenching and tempering and surface nitriding, the stems have good performance of anti-corrosion and anti-friction.
4.Ergonomic hand wheel. It provide longer service life and easier operation.
