- Product Features
- SUNTORK OM series quarter-turn electric control valve actuators are designed to provide torque ranges from 35N‧m to 4500N‧m. The users determine a proper model per load requirements. A planetary gearing is utilized with self-locking to prevent valves from being back driven and provide actuators with stable and reliable operation. ISO 5211 Flange connection is used for mounting actuators to valves and a raised mechanical position indicator is used to enable the operators to identify the valve position. The most distinctive design is clutch-less manual override (except BM-2 and OM-A). The clutch-less design enables the actuators to be changed from electrical control to manual operation without clutch or brake to achieve easier operation thus increases mechanical reliability and decrease the failure rate.

- Explosion-proof quarter turn electric actuators offer torque ranges from 35 N•m to 1,500 N•m. All Models are ISO 5211 compliant and are equipped with a visual position indicator. The manual override can be operated without clutch and brake. OME 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 a mixture of explosive gas atmospheres and combustible dust atmospheres. Temperature group T1 to T4.
