The jacketed thermal insulation hard seal butterfly valve is designed for pipelines handling high-temperature fluids while minimizing heat loss. Its jacketed structure allows insulation material to be applied around the valve, protecting both the media and the environment. The metal hard seal provides excellent durability and leak-proof performance under high temperature and pressure.
This valve is widely used in steam systems, hot oil pipelines, chemical plants, and energy facilities, offering reliable operation, long service life, and enhanced safety for high-temperature industrial applications.
