Characteristics
One-piece welded ball valve has no external leakage and other phenomena.
Since the seat is made of carbon fiber reinforced Teflon seal ring and disc spring, it has strong adaptive capacity to changes of pressure and temperature, to ensure that it will not have any leakage within the marked pressure and temperature range. On account of that the processing of the ball is detected with advanced computer detector, therefore the ball has high processing accuracy. The valve body is made of material the same as that of the pipe, which will not cause uneven stress, or deformation due to earthquake or when vehicles passing, and the pipeline is aging resistant. The seal ring is made of RPTFE material with 20%Carbon, which can ensure no leakage (0%). Directly buried welded ball valve can be directly buried underground. It only needs to build small shallow well on the ground rather than large valve well, which can significantly save construction cost and engineering time. The length of the valve body and the height of the valve rod can be adjusted based on the construction and design requirements of pipelines. The processing accuracy of the ball is very high. The valve is easy to be operated without bad interference. The use of advanced raw materials can guarantee the pressure above PN25. Compared with products of the same specification in the same industry, the valve body is small and beautiful in appearance. The service life is more than 15 years under the condition of normal operation and use of the valve.
