Danfoss ESBE ARC/ARD actuators
The new ESBE ARC/ARD series of high-torque, low-voltage actuators from Danfoss provide 90 degrees of operating range rotation for increased torque ability in mixing or diverting applications in closed-loop hydronic systems. The actuators are designed to assemble to ESBE series 3F and 4F valves but also can be used to control dampers. The ESBE ARD actuator series features built-in safety functionality with a spring return that rotates the valve to a closed position in the event of power failure. Every ESBE ARC and ARD actuator offers easy manual override, and come with a complete valve-mounting kit.
