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 electric actuator can perfect used for 3 point floating type control system, that is commonly used in HVAC field.
Floating control is a variation of On/Off control that requires a fast responding sensor and a slow-moving actuator connected to the final controlled device (valve or damper). When the sensed temperature rises beyond or drops below the set point, the controller sends a signal to activate the actuator on the final device. The actuator starts to slowly drive open or close the hot water valve, increasing or decreasing the heat in the controlled medium. When set point is approached, the actuator stops the final control device (hot water valve) and tries to hold at set point.
So self-locking of electric actuator is the key feature for floating control system. If without self-locking, actuator easily moves away from set point and causes whole system frequently starts and repeats swings in a very small range, which finally result in abrasion of gears.
