International Environmental 71159953 Modulating Actuator 326058-757 While the 10:1 ratio handles

While the 10:1 ratio handles most standard HVAC silicones and acrylic caulks

Field Serviceability: Allows for rapid isolation of components

Optimized for Airflow: Specifically designed for duct applications where ambient wall-mount sensors cannot provide an accurate sample of the air stream

Always verify full-scale current draw before setting the switch for peak resolution

International Environmental 71159953 Modulating Actuator 326058-757 While the 10:1 ratio handlesThe International Environmental 71159953 Modulating Actuator is a critical component for technicians managing HVAC control systems in commercial and industrial facilities. This 24V modulating actuator, often cross referenced as IEC 71159953 or B035 71159953, provides the high torque precision required for VAV systems, fan coil units, and air handling equipment. Designed for proportional control, it effectively regulates airflow or water flow by
