Ventilation butterfly valve for air and HVAC - Reguvale

Ventilation Butterfly Valve — Large-Size Air Flow Control

DN100–DN4000 · Air · HVAC · Fume Extraction · Cleanroom

Reguvale’s ventilation butterfly valves are designed for low-pressure, high-volume air flow control in HVAC systems, industrial ventilation, fume extraction and cleanroom applications. Available in large sizes from DN100 to DN4000 — among the largest in the industry.

Lightweight construction with excellent flow characteristics makes them ideal for air handling units, duct isolation, fume hoods and ventilation mains where pressure drop must be minimized.

Body materials: ductile iron GGG50 (epoxy coated) or carbon steel. Available with manual lever, worm gear, electric actuator or pneumatic actuator for automated air flow control and remote damper operation.
