The Soft Sealing Ball Valve features a floating ball structure and soft-seal seats made of PTFE or RPTFE, achieving rapid opening and closing through 90° rotation. It is suitable for shutting off pipelines carrying water, oil, natural gas, compressed air, and some chemical media, and is primarily used in industrial pipelines operating at normal and medium-low temperatures.
