Danfoss 193B-1603 ARA664 3-Point Floating Motor Actuator with Auxiliary Switch 96 Second Runtime

The Danfoss 193B-1603 is an ARA 600 series motor actuator designed for mounting to ESBE 3-way and 4-way rotary valves. This floating 3-point signal actuator features an integrated auxiliary switch and operates on 24VAC power with a 96-second runtime for 90-degree rotation.

Key Features:

• Floating 3-point control signal with auxiliary switch for status indication
• 96-second runtime provides precise control for hydronic mixing applications
• 24VAC operation for compatibility with standard HVAC control systems
• Compatible with VRG series 3-way and 4-way rotary valves
• Backward compatible with older MG and G series valves
• Improved mounting and operation design for simpler and quicker installation

This actuator is ideal for hydronic heating and cooling systems, boiler applications, and commercial HVAC installations where precise temperature control through mixing valve modulation is required. The auxiliary switch provides valuable feedback for building automation systems and control panels.
