Product Overview
The Danfoss 11166818 is a precision proportional valve actuator engineered for electro-hydraulic control of proportional and servo valves within demanding industrial hydraulic systems. As a key control element in the Danfoss proportional valve platform, this actuator converts an electrical command signal into a precise, proportional mechanical force or displacement that positions the valve spool. This enables infinitely variable control of flow rate and pressure, delivering smooth, accurate, and repeatable actuation. The 11166818 is designed for direct integration with Danfoss proportional valve bodies, ensuring optimal matching of force characteristics, response dynamics, and hysteresis performance for closed-loop and open-loop control applications.
