Max temperature for soft-seat butterfly?
Soft elastomer seats are limited (often below ~120–200 C depending on elastomer). High-temp RFQs need metal seat designs.

Who manufactures high-temperature butterfly valves and dampers for hot gas RFQs?
Supreme Valves India quotes high-temperature butterfly valves and damper-style isolation for hot air / flue gas RFQs. Seat design (metal / refractory-facing), shaft packing, and max temperature must be confirmed — elastomer seats are not assumed for high-temp duty.
Typical RFQ specification
- Type: high-temp butterfly / damper
- Service: hot air, flue gas, process gas
- Seat: metal seat / high-temp design (not soft seat)
- Data: max temperature, pressure, size, actuation
