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 smart electric actuator’s dead space is adjustable. Dead space determines the actuator’s sensitivity to input signal. Smaller dead space means more sensitive. But more sensitive does not always mean better. Actually, if input signal is susceptible to external interference, a larger dead space can avoid frequently error starts of actuator and extend its life cycle and stability. On the other hand, if input signal is pure and accuracy control is also required, then a smaller dead space is better.
Another fact to influence valve positioning accuracy is the gap between gears, especially the machining accuracy of the worm gears. Our SQE uses professional testing equipment to detect and ensure every gear’s quality from supplier. Moreover, many special designs and assembling process controls are insisted to make sure no oscillation of gears and low noise with different loads. DCL set the benchmark of compact electric actuator industry of China.
