PRODUCT OVERVIEW

German standard bellows stop valve is made of metal bellows sealing technology. High performance metal bellows and bellows sealed stop valve are designed with bellows seal, which completely eliminates the shortcomings of rapid aging and easy leakage of ordinary valve stem packing, not only improves the energy efficiency, increases the safety of production equipment, and reduces the maintenance cost and frequent maintenance, It also provides a clean and safe working environment. Widely used in: petrochemical industry, chemical fiber textile, plastic papermaking, electric power steel, printing and dyeing rubber, food and other industries.

Structural features

1. The valve body adopts German 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.

2. When the valve is closed, the conical sealing surface with "scraping effect" can automatically remove surface impurities, which can ensure reliable sealing and longer service life of the valve disc.

3. Double sealing design (bellows + packing), in line with international sealing standards.

4. All bellows pass helium test and all valves pass standard test to ensure zero leakage.

5. Products above DN150 are equipped with special devices to effectively prevent the valve from shaking, noise and internal parts damage during use, and the service life is effectively increased by more than 150%.

6. Various valves can be provided according to working conditions.
