DN1600 Link-type Shaftless Carbon Steel Damper | Large Diameter Industrial Ventilation Butterfly Valve

The DN1600 link-type shaftless carbon steel damper is a high-performance industrial butterfly valve specially designed for large-diameter ventilation, dust removal and flue gas treatment pipelines. Featuring an innovative linkage-driven shaftless (no exposed shaft ends) structure, both the valve body and disc are precision manufactured from high-quality carbon steel, with built-in reinforcing ribs on the disc to enhance the structure. Combining ultra-high structural strength, excellent sealing performance and working condition adaptability, it is an ideal on-off and flow regulation device for large-scale ventilation systems and flue gas pipelines in industries such as power, metallurgy, cement, and waste incineration.

✅ Innovative Link-type Shaftless Structure, Safe & Durable

Adopting a linkage-driven design with no exposed shaft ends, it completely eliminates the protruding shaft head problem of traditional dampers, preventing on-site collision, dust accumulation and jamming risks, greatly improving equipment safety and service life; Meanwhile, it saves installation space and perfectly adapts to complex pipeline layouts.

✅ High-Quality Carbon Steel + Reinforcing Ribs, Superior Deformation Resistance

The valve body and disc are made of high-quality carbon steel Q235B/Q345B, and the disc is equipped with multiple built-in reinforcing ribs (as shown in the figure), which greatly improves structural rigidity, effectively resists pressure impact and thermal deformation of DN1600 large-diameter pipelines, ensuring long-term stable operation without failure.

✅ Tight Sealing & Precise Flow Regulation

Soft seal (NBR/EPDM/PTFE) or metal hard seal structure can be customized according to working conditions, with low air leakage rate and reliable sealing; The disc adopts a streamlined design with small flow resistance, supporting stepless flow regulation from 0° to 90°, accurately matching the working condition requirements of ventilation and dust removal systems.

✅ Multiple Drive Options, Flexible Adaptation to Automation Needs

Supports multiple drive forms such as manual worm gear, electric actuator, and pneumatic actuator (manual/electric models shown in the figure), which can be easily integrated into industrial control systems such as DCS/PLC, adapting to production scenarios with different degrees of automation.

✅ Large Diameter Customization, Meeting All Working Condition Requirements

Tailored for DN1600 large-diameter pipelines, and also supports non-standard nominal diameters, special materials (stainless steel/alloy steel), anti-corrosion coating (epoxy zinc-rich/high-temperature resistant paint) customization, easily coping with various harsh industrial working conditions.

✅ Easy Installation & Maintenance, Low Operation Cost

Adopts standard flange connection such as GB/ANSI/DIN/JIS, easy and quick to install; Reasonable overall structural design with few wearing parts, extremely low daily maintenance cost, greatly reducing the operation and maintenance workload of enterprises.
