1. Bellows protective spatial design: The bellows is sealed within a closed space, protected from direct impact by medium, pressure, and temperature.
2. The extended, multi-layered, torsion-resistant, and long-lasting corrugated pipe completely revolutionizes the opening and closing lifespan of domestic corrugated pipes, with a maximum of up to 10,000 cycles.
3. The valve body adopts German precoated sand casting technology, which greatly improves the surface smoothness and mechanical properties of the valve body, reduces the occurrence of pores, sand holes, and cracks, and enhances the tensile strength of the casting.
4. When the valve is closed, the conical sealing surface with a "scraping effect" can automatically remove surface impurities, ensuring reliable sealing and a longer service life for the valve disc.
5. The dual sealing design (corrugated pipe + packing) meets international sealing standards.
