Explosion-proof Electric Actuators

Sun Yeh explosion proof electric actuators are designed for hazardous environments, ensuring both safety and stable operation in risk applications such as petrochemical, natural gas, and chemical industries are structured as flame-proof and combustible dust-proof. The directive and standard marking is II 2 GD Ex db IIB T4 Gb, Ex tb IIIC T130°C Db. They are classified as Zone 1 or Zone 2, containing Group IIA and Group IIB gases, Zone 21 or Zone 22, containing combustible dust atmospheres or a mixture of explosive gas atmospheres and combustible dust atmospheres. It is suitable for temperature classes T1 to T4. No matter quarter turn, spring return fail safe, or linear actuators, these actuators carry forward Sun Yeh’s hallmark quality and durability, delivering safe and reliable actuation for critical industrial processes.
