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.

220VAC Quarter Turn Actuator,
S4 Intermittent Valve Actuator,
4mA Valve Actuator
S4 intermittent duty rate quarter turn actuator with 1200 times/hour operation
DCL modulating type electric actuators are S4 intermittent periodic duty operation. Actuator sequential, identical starts, runs and rests cycles with rated load. As the starting current affects temperature rise, if motor is not proper designed, actuator will be easily shut down during high frequently starts by thermal overheat protector in motor and actuator body will be very hot.
Actuators have been rigorous tested by CSA and certified per UL and CSA standard. In chemical and food & beverage industry, the fluid needs to be controlled very precisely, so the actuator start frequency is very high. 1200 times/hour can reach world leading level and can meet requirements of above industries.
