1. Bellows protective space design: The bellows are sealed in a confined space, unaffected by media, pressure, or temperature.

2. Extended, multi-wall, anti-torsion, long-life bellows, completely refreshing the opening and closing life of domestic bellows, up to 10,000 cycles.

3. The valve body adopts German film-coated sand casting technology, which greatly improves the surface finish 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 of the valve disc and a longer service life.

5. Dual sealing design (bellows + packing), complying with international sealing standards.

6. All bellows are 100% helium tested, and all valves are 100% standard tested to ensure zero leakage.

7. Products above DN150 are equipped with a special device (patented by our company) to effectively prevent valve trembling, noise, and internal component damage during use, extending service life by over 150%.

8. Various valve disc designs can be provided according to working conditions, such as throttling valve discs, globe check valve discs, etc.
