Midea Group - ChinaDCL has been our partner and supplier for over 6 years. Their electric actuators are used to drive our guide vane of our refrigeration compressors. Our central air conditioners are serviing customers in HVAC all around the world with DCL's products. They continuously provide very reliable products and very ontime service to support us. -
Valve Solution Inc. - USADCL has been our ODM/OEM plant for about ten years. Their products are designed per UL and CSA standard and passed CSA certification. Very few Chinese manufacturers can produce USA's standard electric actuaotrs with such good quality, that is why we choose them as our long term partner. We are expecting DCL can keep innovation. -
WESA Armaturen GmbH - GermanyWith 15 years cooperation with DCL, we are very satified with DCL's products. DCL regards quality first and their employees are very rigorous to products. They always do many experiments and tests to confirm their new designs and upgrade. We are also amazing about their wonderful quality control for the outsourcing parts.
Fail Safe Return 600Nm 45S IP68 ATEX CSA Explosion Proof Valve Actuator
| Name | Explosion Proof Fail Safe Electric Actuator | Standard Torque | 50Nm To 600Nm |
|---|---|---|---|
| Standard Time | 20s To 45s | Package | Small Package |
| Type | Quarter Turn Actuator | Feature | Over Torque Protection |
The DCL-Ex explosion-proof electric actuator range offers an optional fail-safe module for hazardous-area valves requiring a defined response to external power loss. During normal operation, the internal circuit charges a supercapacitor or battery. When external power is unexpectedly disconnected, stored energy powers the motor to move the valve to a preset fully open or fully closed position, or retain its current position. Once external power returns, the actuator automatically exits fail-safe mode and resumes normal operation.
The fail-safe components are integrated within the actuator housing, supporting compact equipment layouts. The range allows mounting through 360° and provides ISO 5211 mounting interfaces. Standard output torque ranges from 50 to 3000 Nm, with an IP68 enclosure and a stated ambient-temperature range of -25°C to +55°C. The literature specifies stored energy for at least four full-stroke operations; available movements under actual valve load and fail-safe operating time should be confirmed for the selected configuration.
The product documentation includes ATEX, IECEx and CSA certification information, with markings such as Ex db h IIC T4 Gb and Class I, Division 1, Groups C and D, T5/T6. Selection should verify the certificate scope, gas group, temperature code and installation conditions for the specific model, together with valve torque, the required power-loss position and control mode.
