CSA ATEX IP68 50Nm~3000Nm Explosion-Proof Quarter-Turn Electric Actuator for Industrial Valve Automation

• Standard output torque from 50 to 3000 Nm, with maximum torque from 65 to 3900 Nm.

• IP68 enclosure and a stated ambient-temperature range of -25°C to +55°C.

• Explosion-protection markings include Ex db h IIC T4 Gb and Ex h tb IIIC T135°C Db.

• North American ratings include Class I, Division 1, Groups C and D, T5/T6, and Class I, Zone 1.

• Available with on-off, position-feedback or modulating control.

• Modulating versions accept 4–20 mA, 1–5 VDC or 2–10 VDC input and provide 4–20 mA position feedback.

• Basic modulating error is no more than ±1%, with repeatability error no more than 1%.

• ISO 5211 direct-mount options and model-dependent DC12V, DC24V, AC110V, AC220V or AC380V power supplies.

• Optional over-torque protection, anti-condensation heating, Modbus RTU and fail-safe return.

The DCL explosion-proof electric actuator range supports quarter-turn valve automation in oil and gas, petrochemical, chemical, metallurgy and other industrial applications. Models from DCL-Ex05 to DCL-Ex300 provide standard output torques from 50 to 3000 N·m for ball valves, butterfly valves, plug valves and other compatible rotary valves.

The range features an IP68 enclosure and a specified ambient temperature range of −25°C to +55°C. Hazardous-area options include ATEX/IECEx-certified configurations and North American Class I, Division 1, Groups C and D configurations.

Selection must match the installation’s gas or dust classification, temperature requirements and applicable certification. Confirm the exact model, complete explosion-protection marking and certificate conditions before specifying the actuator. IP68 protection alone does not establish hazardous-area suitability.

Available configurations include on/off control, dry-contact status feedback, potentiometer feedback and modulating position control.

Modulating versions accept 4–20 mA DC, 1–5 VDC or 2–10 VDC command signals and provide 4–20 mA DC position feedback. Their specified basic error is no greater than ±1%, with repeatability error ≤1%. These figures describe actuator positioning performance rather than the flow-control accuracy of the complete valve system.

Optional over-torque protection interrupts the motor circuit when torque reaches a preset threshold, helping protect against excessive loading during valve obstruction.

An optional stored-energy fail-safe configuration uses a supercapacitor or battery, depending on the model. Following external power loss, it can drive the valve fully open or fully closed, or retain its current position, according to the selected setting.

Before ordering, confirm valve operating torque, mounting dimensions, supply voltage, travel angle, operating time and control signals. Optional functions and accessories must also match the selected model and remain within the applicable certification scope.
