Product Introduction:
The electric single-leaf butterfly valve features a one-piece welded valve body with a single internal circular butterfly plate.
An electric actuator drives the valve stem, causing the butterfly plate to rotate 0°~90°,
changing the flow area of the air duct and achieving the opening and closing of the gas pipeline and coarse adjustment of the airflow.
Mainly used in low-pressure, high-flow-rate air ducts for media such as air, hot air, dusty flue gas, exhaust gas, and kiln exhaust.
Widely used in dust removal equipment, desulfurization and denitrification systems, boiler flues, metallurgical systems, and building material ventilation systems.
Standard design is unsealed, resulting in slight leakage; a metal hard seal can be customized for applications requiring tight sealing; a soft seal is available for clean air at normal temperature.
Main Features:
Simple robust structure, fewer spare parts, low failure rate and easy maintenance.
Extremely low flow resistance under fully open condition, saving fan power consumption.
Good high-temperature resistance, ideal for hot flue gas working conditions.
Competitive cost compared with multi-leaf dampers of the same size.
Multiple connection options: flanged, wafer, butt-welded.
Optional on-off / modulating / explosion-proof electric actuator.
