Recently, a batch of pneumatic flanged ventilation dampers has finished assembly and inspection for delivery. Available in DN150, DN200, DN300, DN400 and DN600 sizes, these dampers are supplied in carbon steel and stainless steel body options for global buyers engaged in industrial ventilation, waste gas treatment, heat supply pipelines and metallurgical dust removal projects.

Also known as ventilation butterfly dampers, this series adopts integrated flanged structure equipped with pneumatic actuators to support remote on-off and flow regulation. The valve body features high rigidity and optimized shaft sealing to minimize leakage. Stainless steel air dampers deliver excellent anti-corrosion and high-temperature resistance for humid and corrosive flue gas conditions, while carbon steel versions offer cost-effective performance for regular hot air and air conveying pipelines.

Key advantages include full size coverage for small-to-large piping systems. Pneumatic actuation ensures fast response. Matched solenoid valves and limit switches allow easy integration with automatic control systems. Flanged connection simplifies on-site installation and maintenance. Low flow resistance guarantees high ventilation efficiency for both shut-off and continuous air volume adjustment.

Suitable media include ambient air, hot air, flue gas and dust-laden gas. Widely used in metallurgical dust removal, industrial waste gas purification, HVAC ducts, waste incineration supporting pipelines, cement plant hot air circulation and water treatment ventilation systems. Custom sizes, anti-corrosion coatings and high-temperature upgrades are available to meet international project standards.

Every damper valve undergoes strict tightness and operation tests before shipment. We serve global EPC contractors, equipment manufacturers and trading partners, offering complete datasheets, drawings and customized solutions.
