High pressure forged steel floating ball valve mainly has two types of seal, one is hard seal, the other is soft seal. They have their own advantages. Compared with soft seal, the difference between hard seal and soft seal is that the latter is soft seal seat, while the former's ball and valve seat are hardened by special process, and there are many ways of hardening, such as integral nitriding, flame spraying and stacking The selection of hardening mode depends on the working medium or the user's requirements; the hard seal is especially suitable for the medium with high temperature and various dust and solid particles; the soft seal is suitable for water, steam, oil and other clean media; the high-pressure forged steel floating ball valve is widely used in petroleum, chemical, metallurgy, papermaking, electric power, etc Mining and other industries.

1. The main parts of high pressure forged steel floating ball valve are forged products with dense materials and guaranteed safety performance.  
2. General products, mature structure, compact, simple, convenient maintenance.  
3. The soft sealing ball can be polished and nickel phosphorus plated according to the user's requirements, while the hard sealing ball is made of super British speed spraying wear-resistant alloy powder, and the valve seat is overlaid with Stellite cemented carbide and sprayed with other super wear-resistant alloy materials.  
4. The sealing surface is finely ground, and the sealing is reliable.  
5. Full diameter channel design, small flow resistance and large flow capacity.  
6. The valve rod anti fly out design is safe and reliable. The anti-static function can be designed according to the requirements.  
7. A variety of drive options: manual, worm gear drive, pneumatic, electric, hydraulic, etc.; can also be used with automatic pneumatic instruments.
