S-Zorb technology is developed by COP(Conocophillips) company, which is mainly used to catalyze gasoline desulfurization。Because the high efficiency and low lost of octane of S-Zorb technology generation 2, and gasoline after desulfurization meet National IV Standard, S-Zorb technology becomes more and more widely-used。Currently, 20 sets of S-Zorb desulfurization equipment are on construction and constructed in our country, and the Programmable Rigidity Seal Ball Valve with Advanced Parameters and High-performance that S-Zorb gasoline desulfurization equipment use are all imported。Because S-Zorb Programmable Rigidity Seal Ball Valve with Advanced Parameters and High-performance are mostly used in rough conditions, the whole equipment has to stop in case of its troubles, which will cost a lot；Besides, valve are dependent on import for long, the time of replacement and maintenance is long, so S-Zorb Programmable Rigidity Seal Ball Valve with Advanced Parameters and High-performance need to be domestic urgently.

      Through two years maintenance and use of import valves of S-Zorb equipment and test use of products, Kingdom Flow Control Co., Ltd. has learnt basically the working and quality requirements, design, material, manufacture, process, test and examination, use, installation and maintenance of valve of Programmable Rigidity Seal Ball Valve with Advanced Parameters and High-performance in S-Zorb equipment. Valves we maintain, design and manufacture can satisfy the requirement of most
