    characteristics of pvc compact ball valve

    Have already visited: 11412/16/2021  

    With the continuous development of domestic industry, the demand for PVC compact ball valve used on the pipeline also increases, the requirements for PVC compact ball valve are becoming higher and higher, users choose PVC compact ball valve, special attention to the valve has good sealing performance to prevent the leakage of media. Because the reliability of imported PVC compact ball valve is better, so the user uses imported PVC compact ball valve for important parts, but the price of imported ball valve is expensive, the delivery cycle is longer, and the after-sales service is not convenient, which seriously affects the operation of the whole pipeline. In order to reduce pipeline costs and realize the localization of PVC compact ball valves, domestic manufacturers are constantly improving on the quality and sealing reliability of domestic PVC compact ball valves, and strive to replace imported PVC compact ball valves.


     demand for PVC compact ball valve


    PVC compact ball valve has good thermal insulation characteristics, and the valve diameter is consistent with the pipe diameter, and can effectively reduce the heat loss of the medium in the pipeline. It is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport high viscosity media that can be solidified at normal temperature.


    Usually PVC compact ball valve radial sealing is the use of O-ring sealing structure, so that the use of the temperature of the whole valve is directly affected by the o-ring temperature, the current USE of PVC compact ball valve O-ring is fluorine rubber, and the use of fluorine rubber temperature within 200℃, and can not be used in this limit temperature for a long time. Far from meeting the requirements of many media in the market, such as the working medium for rosin, the requirements of PVC compact ball valve temperature is 300 ℃, so as to facilitate rosin medium to obtain more ideal fluidity, the traditional O ring as a sealing part, can not meet its requirements.
