The sealing face is built up with Co-based carbide alloy, leaving a better wear-ability, corrosion and scrap resistance and a longer duration. 3. Small opening pressure, the disc can be opened fully with a very small pressure differential. 4. Inside-set bolt-bearing structure reduces leakage and reliable use. 5. PN>=*6.0MPa (Class***0), the middle cavity uses a self tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as ensure the sealing performance. 6. Different parts materials and different sizes for flange, butt-welding are available for reasonable combination according to different working facts and customers’ requirements.
