Design Advantage: 1. Low valve lifts ——— low impact force,long life 2. The mushroom-shaped head is designed spherical surface, liner contact with the sealing surface of the valve seat ——— perfect sealing property 3. Special hardening treatment for the sealing surface of the valve seat and the guide hole of the valve deck ——— reduce wear 4. Honeycomb design ——— the same area, the most mushroom-shaped head 5. Single valve head ——— easy to use and maintain 6. High-performance shock resistance PEEK mushroom-shape valve head ,low wear, low noise 7. Soil Resistance ———— Resistance to liquid and impurities and oil viscosity, high reliability Suitable Area: 1.Medium-high pressure condition 2.Medium-high revolution rate ,Rev<1500 rpm 3. Oil/Non-oil condition
