ball valve's brief introduction:

hard seal ball valve USES the national standard of casting, forging production, sealed to the metal hard seal structure, the sphere for solid sphere nitriding treatment. The valve ball valve seal surface weld hard alloy, has the characteristics of high temperature resistant, wear resistant, is the most ideal choice for harsh conditions. Ball valve is mainly used in high temperature medium pipeline, such as steam, thermal oil, food, chemical raw materials, etc. Our company produces the high temperature ball valve up to 600 ℃ ( 310 s high temperature resistant body) , if the corrosive medium, the temperature can drop along with the strength of corrosion. Sealing principle of this product is similar to ordinary ball valve, ball is floating ball structure, also depend on medium pressure cauda equina play an effective seal.
