Electric damper actuator/Rotary air damper actuator

Our DKJ electric rotary valve actuators has 40 years produce history, they have the advantage of 

simple structure, practical and economical use. 

This series rotary actuator normally used for control industrial ball valve, butterfly valve, damper etc.
