Imported Pneumatic Air Damper Valves (Imported Pneumatic Flue Damper Valves, Imported Pneumatic High-Temperature Damper Valves, Imported Pneumatic Flue Regulating Damper Valves)
Brand: Germany's VordeWODE
The imported pneumatic air ventilation butterfly valve is a non-sealed rotary butterfly valve used in ventilation ducts. It is designed and manufactured with a structure that features a mid-line disc plate welded to a short structural steel plate, serving as a flow regulator or on/off control for gas mediums. The pneumatic air ventilation butterfly valve has low flow channel resistance, high flow coefficient, light weight, and fast opening and closing. When paired with a valve positioner, it can achieve proportional adjustment, making it particularly suitable for controlling gas flow in large-diameter, high-flow boiler flue gas ducts.
Advantages of Imported Pneumatic Butterfly Valves:
1.Remotely control valve openings and adjustments for time and labor-saving, as well as reduced人工costs.
2.Internally free of rods, bolts, etc., reliable operation, long service life. Suitable for multi-station installation, unaffected by medium flow direction.
3.Designed and manufactured with a new structural form using mid-line disc plates and short structural steel plates welded together, it boasts a compact structure, light weight, easy installation, low flow resistance, and high flow volume, while mitigating the effects of high-temperature expansion and offering convenient operation.
