Design Features
1. Liftable sealing surface of wedge can scrape of f the adhered things on the sealing surface and
automatically eliminate the impurities.
2. The Stainless steel wedge can prevent sealing leakage due to corrosion.
3. The integral stainless steel materials can prevent corrosion and damage.
4. The scientific back seal packing box design makes the bak seal safe, effective and durable.
5. The triangle supporter ensures necessary mechanical properties.
6. V shape wedge can serve as control valve.
7. The guide block on the valve body enables the wedge to move correctly and extrusion block provides
effective sealing for the wedge.
8. The design of valve body reinforcing rib can enhance the body strength.
