The ESBE 81 24V 3P actuator is a rotary actuator for motorised control of mixing/rotary valves in hydronic (heating and cooling) applications. It is designed for simple and reliable valve position control using a 3-point signal. With its short repositioning time and sufficient torque, it is suitable for standard mixing circuits where a swift control response is required. This variant corresponds to series 90, designation 91. The ESBE 81 model is being replaced in the ESBE range by actuators ARA600(12050200) , which maintain proportional control and are intended for the same types of mixing installations.
