                  [Valve features]

                  1, simple structure, small volume, light weight, easy to install and use only, not to burden the pipeline, after the repair and replacement are very convenient.
                  2, the fluid resistance is small, the sealing surface by medium erosion and erosion.
                  3, The utility model has the advantages of labor saving, good manufacturability and wide application range.
                  4, forged steel valve with self sealing design, the surrounding environment the greater the pressure, sealing it more reliable, do not worry about high negative impact on the use of the process, can not competent in high-pressure environment application in other valves.
                  5, because of the performance, technical characteristics, special conditions, so that the product has also formed other products can not be replaced by features.

                  [Adaptive condition]
                         Forged steel gate valve applies to ANSI, Class 150~2500, operating temperature <600℃ of petroleum, chemical, thermal power plants and other working conditions on the pipeline, cut off or switch on the pipeline medium.
