Definition of Three-Piece Instrument Ball Valve

The three-piece instrument high-pressure ball valve is suitable for various pipelines with a pressure range of PN1.0Mpa-20Mpa and an operating temperature range of -29~180℃ (with reinforced PTFE sealing rings) or -29~300℃ (with para-phenylene sealing rings). It is used to cut off or connect the medium in the pipeline. By selecting different materials and connection methods, it can be widely applied in fields such as petroleum, chemical engineering, metallurgy, power plants, water treatment, food processing, Chinese patent medicine extraction, beverages, protein processing, biological fermentation, and HVAC (Heating, Ventilation, and Air Conditioning).
