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.
200Nm 2~10VDC 40W Modulating Explosion proof valve actuator
|Explosive-proof Grade||Exd II BT4Gb||Protection Class||IP67|
|Ambient Temperature||-20℃~+60℃||Motor Power||40W|
DCL explosion proof electric actuators are widely used in potential environment of flammable and explosive, such as petroleum, chemical, power plant, liquid gas, winery and metallurgy etc. To ensure workers are away from danger, explosion proof is a must. For different industries, zones and divisions, different explosion proof grade is required.
Actuators with ExdIIBT4 and Group C, D T4 grade can be used in 90% explosive gas atmospheres except for colliery. The maximum surface temperature of actuator is less than 135℃ and 300.6F during severe duty applications. Over 10 years of safety operations in China, now all series anti explosion actuators are on rigorous test process of CSA and will be certified in Q3 of 2020.

Control Circuit of Type E
The Servo-controller is located inside of the actuator. It receives command of the central control system and drives valve to proper opening position according to varying conditions of variables(flow,pressure,temperature,fluid level) in the pipe.
Adopt character of service of S4 intermittent type, working frequency reaches 1200 times/hour.
The unique circuit design, imported technical grade electronic parts and components and modern making technology of circuit board of the DCL ensures high quality and reliability of the servo-controller. The circuit board with resin plastic package makes shock and humidity resistance better.the unique electronic brake function makes actuator dead-beat when position is fixed, the period of damping character is zero times(standard: Less than 3.5 times)
