310S butterfly valve

The following is a comprehensive summary of the technical parameters, application scenarios, and market data of 310S butterfly valves and 310S valves:

1、 Product Definition and Core Features
310S valve is a special valve made of 310S austenitic stainless steel (UNS S31008) as the main material. Its temperature resistance range covers -196 ℃ to 800 ℃, and it exhibits excellent creep resistance and corrosion resistance in high-temperature oxidative environments such as cogeneration and molten salt energy storage.
The 310S butterfly valve, as a representative product of this series, adopts the following innovative design:
Sealing technology: High temperature soft sealing material (such as graphite wrapped gasket) and metal hard sealing composite structure, with a leakage rate of ≤ 0.5% under a temperature difference of 780 ℃.
Channel optimization: Control the medium flow velocity within 12m/s through CFD simulation to reduce particle erosion.
Execution mechanism: IP68 protection level electric actuator, supporting MODBUS RTU protocol and DCS system integration.
