Application
The 400606 thermostatic actuator is well-suited for use in hydronic heating systems, hot water distribution, and steam applications where automatic, self-contained temperature regulation is required. The cross ambient filled capillary compensates for changes in surrounding temperature, ensuring that the actuator responds only to the process fluid temperature — delivering consistent, reliable valve positioning throughout the operating range.
