The Vahn-Tech Series VT-OMX Explosion Proof Electric Actuators offer torque ranges from 35 Nm to 1,500 Nm (310 in-lb to 13,280 in-lb). All models are ISO 5211 compliant and are equipped with a visual position indicator. The manual override can be operated without clutch and brake. VT-OMX series explosion-proof quarter-turn electric actuators are structured as flame-proof and combustible dust-proof. The directive and standards marking are II2GD Ex db IIB T4 Gb, Ex tb IIIC T130°C Db. They are classified as Zone 1 or Zone 2, containing Group II A and Group II B gases, Zone 21 or Zone 22, containing combustible dust atmospheres or explosive gas atmospheres and combustible dust atmospheres. Temperature group T1 to T4.
