J61H, J61Y PN200 - PN320 high temperature cut-off valve is suitable for the nominal pressure butt welding power station PN200 - PN320 and P54 - P57/170V/100V, the working temperature of 540℃ or less (including P57/170V working temperature is 570℃) of oil, chemical industry, hydropower and thermal power plant all kinds of piping system, cut off or connect pipe medium.

The "power station cut-off valve" is also referred to as the special valve of the power station, which is mainly applicable to the pipelines of various systems of the thermal power station, cutting or connecting the pipeline media. Applicable media: non-corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the characteristics of the performance technology and the special conditions of the working conditions, the products cannot be replaced by other products.
