Solution Areas

Shanghai Rogers Cryogenic Butterfly Valves are designed for extreme sub-zero (-40°C) environments, serving LNG storage/transport, liquid oxygen/nitrogen systems, cold chains, and polar oil/gas fields. They isolate flammable/explosive media in LNG tanks (-162°C), control corrosive flows in ultra-low temp reactors, and regulate refrigerants in cold logistics. Constructed with austenitic stainless steel/nickel alloys to resist low-temp embrittlement, they feature multi-layer PTFE/metal seals for zero leakage, anti-cavitation hardened discs, and vibration damping. Insulated long-neck bonnets, electric tracing, and IoT monitoring ensure reliability down to -196°C, handling high pressure differentials, salt spray, and hazardous conditions in LNG/petrochemical sectors.
