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.

Heavy Duty Rate Multi Turn Actuator for PVC diaphragm valve/shut-off valve/needle valve
- Turns and torque can be set to match with different size of diaphragm valve
- Heavy duty DC brushless motor provides large torque and high speed with small inertia force
- High pressure die cast aluminum alloy housing with external power coated
- IP 67/NEMA 4X sealing grade/weather proof for indoor and outdoor use
- Smart mini control board inside to provide over current protection
- Permanent lubricated gear drive without maintenance
- Double direction over torque protection
DCL-MZZ multi-turn electric actuator uses over torque protection type to close valve to make sure valve is fully sealed. Since diaphragm valve and small globe valve linear move by rotate drive, and these valves commonly need to be sealed by an over normal torque which is like screwing cap to a bottle.
So for closing direction, an large over torque protection is set, to make sure valve is totally sealed. While, we can see that if the torque of the closing direction and the opening direction is the same, then valve can not be opened, which is also same as that when unscrewing the cap from a bottle, we need even larger torque than screw it. So the opening direction over torque protection is 1 second later than motor starts moving to avoid motor stuck on the fully close position.
|Withstand Voltage Class||500VAC 1minute|
