Electromagnetic ventilation butterfly valves are driven by electric actuators or electric devices, enabling on-line or remote centralized control of the valve plate's opening and gas flow regulation. They are used in dust collection or removal systems, metallurgy, and building materials ventilation systems, installed in various exhaust gas, cold and hot dust-laden gas ventilation pipelines to control gas flow.
Features of Electric Air Vent Butterfly Valve
Electrical Ventilation Butterfly Valves are primarily composed of an electric unit, electric actuator, housing, connecting flange, and baffle, etc. Made from carbon steel or stainless steel, wear-resistant manganese steel, and other materials, they are cut and welded according to size requirements. They are unaffected by gas flow and are a non-sealed type of valve, suitable for various high and low-temperature and corrosive working conditions.
Electromagnetic ventilation butterfly valves feature a reasonable structural design, unaffected by temperature difference expansion. They offer smooth opening and closing, utilize flange connections for easy installation, and boast a long service life.
