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.

DCL explosion proof electric actuators can reach 10000 times full range open and close life cycle with rated load and 200000 starts for modulating type. Spur gears are made of CR40 alloy steel with soft nitriding. Compared to powder metallurgy gears, CR40 alloy steel gear is harder and tougher. Commonly, gears are processed by blackening. But DCL newly adopt soft nitriding treatment to improve strength and abrasion resistance gears comparing to blackening. This soft nitriding process can decrease friction noise and highly increase gear surface anti-corrosion capability. Moreover, this new process is also more friendly to environment.
Actuators are under rigorous tests of CSA China office per ATEX/CSA/UL standard and will get CSA certification in Q4 2020.
