Explosion-Proof Electric Butterfly Valve

The explosion-proof electric butterfly valve is assembled by combining a flanged butterfly valve (wafer-type butterfly valve) with an explosion-proof electric actuator. It is a specialized explosion-proof valve designed for use with flammable and explosive gases, liquids, or dust media. All equipment undergoes anti-static treatment, with protection ratings typically at IP65, IP67, or IP68, and explosion-proof ratings marked as Exd IIB T4 or CT4.
