    Product description

    The three-piece ball valve is suitable for cutting off or connecting various pipelines with a working temperature of -29~180°C (the sealing ring is reinforced polytetrafluoroethylene) or -29~300°C (the sealing ring is para polystyrene). medium in the pipeline. Different materials are selected, which can be applied to various media such as water, steam, oil, nitric acid, and acetic acid.

    Features
