Product Overview
The Danfoss 11166829 is an electrohydraulic valve actuator engineered for precise, proportional control of hydraulic directional control valves within demanding industrial systems. As a key component in the Danfoss electrohydraulic actuation platform, this unit converts an electrical command signal into a proportional hydraulic pilot pressure, enabling smooth, infinitely variable spool positioning in standard directional control valves. This actuator is designed to interface directly with Danfoss proportional and directional valve bodies, providing reliable, repeatable flow and directional control for high-cycle industrial machinery. Its robust construction and sealed electrical interface ensure dependable performance in harsh environments where vibration, temperature fluctuation, and contamination are present.
