The power station shut-off valve is suitable for the pipelines of various systems of thermal power plants to cut off or connect the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the power station valve is characterized by high temperature and high pressure, and a unique self-sealing design. The higher the pressure, the more reliable the sealing.
