ASTM A352 LCC Plug Valve

An ASTM A352 LCC plug valve is a quarter-turn rotary isolation valve cast from low-temperature carbon steel (LCC) and engineered to handle high-pressure fluids in sub-zero climates. The A352 LCC material formulation undergoes specialized heat treatment to guarantee exceptional impact toughness and structural ductility down to -46°C (-50°F), preventing brittle fracture failures. By rotating a tapered or cylindrical plug within the valve cavity, it provides rapid, reliable line isolation and excellent resistance to abrasive solids and slurries. Pipeline contractors and polar process layout engineers can protect high-pressure pipelines from low-temperature brittle fractures by importing certified ASTM A352 LCC plug valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
