Product Overview
The Danfoss PVEH 120 (S7) Proportional Valve Actuator, part number 11166777, is a high-performance electro-hydraulic actuation unit engineered for precise control of proportional directional and flow control valves within demanding industrial hydraulic systems. Operating on a proven hydraulic pilot principle, the PVEH series converts a low-power electrical command signal into a proportional hydraulic output pressure that strokes the main valve spool with exceptional linearity and repeatability. The “S7” designation identifies the specific solenoid and connector configuration, while the 120 model delivers a controlled pilot pressure range suitable for a broad spectrum of Danfoss proportional valve platforms. This actuator is a critical interface component in closed-loop and open-loop motion control architectures, enabling smooth, shock-free acceleration and deceleration of actuators, cylinders, and motors. As a genuine Danfoss component, it ensures seamless integration, long service life, and consistent performance in the most rigorous industrial environments.
