The SAF15 High Air Damper (also termed Hot Blast Valve or Blocking Air Damper Valve) is engineered by SASTAR—a leader in precision airflow solutions for industrial extremes.

Designed as a high-temperature flue baffle or butterfly valve, it excels in environments up to 1300°C, leveraging advanced materials and anti-jamming innovations for unmatched reliability.

Core Engineering & Material Excellence

Ultra-High Heat Resistance:

Withstands phased temperature ranges (450–650°C, 650–1150°C, 1150–1300°C), ideal for kilns, incinerators, and power plants.

Zero-Leak Performance:

Leakage rates as low as 0–1% (options: 1.5%/3%), ensuring energy efficiency and emission compliance.

Anti-Jamming Air Purge:

Integrated purge holes prevent dust accumulation—critical for cement/steel industries where particulate buildup causes valve failure.

Robust Material Suite:

Valve plate/seats: 0Cr25Ni20 (310S stainless steel); shaft: Cr18Ni9Ti.

Optional alloys (316L, 12Cr1MoV) for corrosive/abrasive environments.

Custom Geometry:

Supports square, round (e.g., High Temperature Round Butterfly Damper), or hybrid shapes to fit unique duct layouts.

Why Choose SASTAR's SAF15 High Air Damper?

SASTAR merges industrial authority with agile customization to solve high-heat airflow challenges.

Whether deployed as a Hot Blast Valve in steel mills or a Blocking Air Damper Valve in power plants, the SAF15 High Air Damper delivers precision, durability, and near-zero leakage—backed by global technical support.

Trust SASTAR to engineer resilience where temperatures peak and reliability is non-negotiable.

The high temperature butterfly valve (high temperature flue baffle) valve body is lined with valve plateand valve seat which are made of 0Cr25Ni20 - The shaft is made of Cr18Ni9Ti heat-resistant stainlesssteel.

The high temperature butterfly valve (high temperature flue baffle) has high strength, wear resis.

tance, corrosion resistance and other properties.

The structure is equipped with air purge holes, which facilitates the normal operation of the valve underhiah temperature conditions, reduces dust accumulation, and prevents the valve plate from gettingstuck, thereby ensuring that the valve plate can be opened flexibly.

The high temperature butterfly valve(flue baffle) can also be designed and manufactured into a square shape, or a round top with a squarebottom to meet the needs of flues with different cross-sectional shapes.
