Product Overview: Precision Airflow Control for Extreme Environments

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.

Multi-Industry Applications

Applicable temperature 450℃c~650°c,650°c~1150'c,11509c1300 Leakage rate 3%, Low leakage 1.5% Lined with refractory material ceramic fiber. The SAF15 High Air Damper operates as a critical Blocking Air Damper Valve in:

Power Generation: Flue gas desulfurization (FGD), boiler draft control.

Steel & Cement: Kiln exhaust management, preheater gas flow.

Waste-to-Energy: Incinerator emission systems.

Glass Manufacturing: Furnace airflow regulation.

Chemical Processing: High-temperature reactor venting.

Experience & Expertise

10+ years specializing in extreme-environment flow control, with deployments across global power/steel sectors.

ISO-certified R&D leveraging materials science (e.g., ceramic fiber refractory lining for 1300°C resilience).

Customization Capabilities

Tailored Designs: Bespoke dimensions (DN 100–3000mm+), shapes (round/square/hybrid), and actuation (manual/electric/hydraulic/pneumatic).

Material Flexibility: Alloy optimization for corrosion/heat resistance (e.g., 310S for sulfidic environments).

Service & Trust

End-to-End Support: Engineering consultation → prototyping → installation.

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.
