Electric Damper Butterfly Valve (DN40-DN1200) – For Air & Flue Gas Control | DELCO

✅Optimized for Air & Gas Regulation
Unlike standard liquid valves, this damper is specifically engineered for low-pressure gas media (< 0.25 Mpa). It allows for precise modulation of airflow in HVAC ducts, desulfurization (FGD) systems, and industrial exhaust stacks with minimal pressure loss.
✅Lightweight Disc & Low Torque
The streamlined valve disc design reduces weight and flow resistance. This low-torque characteristic allows for the use of compact electric actuators (DELCO-10 Series), significantly reducing energy consumption and equipment cost compared to heavy-duty liquid valves.
✅Smart Electric Automation
Integrated with the DELCO Electric Actuator, featuring a high-visibility indicator and manual override. It supports On/Off or 4-20mA Modulating control to maintain optimal air-to-fuel ratios in burners or stable static pressure in ventilation ducts.
✅Durable Construction for Industrial Exhaust
Available in materials ranging from Cast Iron for standard HVAC air to Stainless Steel (304/316) for corrosive flue gases. The simple structure prevents dust accumulation, making it ideal for particulate-laden environments.
✅Space-Saving Wafer Connection
The compact wafer-style body fits easily between standard pipe flanges (GB, ANSI, DIN), reducing installation space requirements in tight plenum chambers or crowded mechanical rooms.
