AME 655/655 GA Modulating & Three Point Control Actuator

Brand: Danfoss

Actuators are primarily designed to regulate valve in the respond to the demand of a controller in District Heating/cooling, Heating, Ventilating and Air conditioning systems. 

Actuators AME 655 can be controlled by electronic controllers with modulating or 3-point control output.
Features
