Product Overview
The Danfoss PVEH 120 (Part Number: 11166777) is a high-performance electro-hydraulic proportional valve actuator designed for precise control of hydraulic directional and proportional valves. This advanced electrical actuator converts a variable electrical input signal into a proportional hydraulic output, enabling infinitely variable control of flow rate and directional spool positioning. The PVEH series is engineered for demanding industrial environments where accurate, repeatable, and dynamic response is critical. As a core component in Danfoss proportional valve systems, the PVEH 120 ensures smooth actuation, minimal hysteresis, and excellent linearity, making it an ideal choice for closed-loop and open-loop hydraulic control circuits.
