Product Overview
The Danfoss PVEH 32 (part number 157B4032) is a high-performance electro-hydraulic proportional valve actuator designed for precise, continuous control of hydraulic directional and proportional valves within demanding industrial systems. Operating on a proven proportional solenoid principle, this actuator converts a variable electrical current input into a proportional mechanical force and stroke, enabling infinitely variable spool positioning for accurate flow and pressure modulation. As a member of the Danfoss PVEH series, the PVEH 32 is engineered for high-force actuation with excellent linearity, low hysteresis, and fast dynamic response, making it a critical control interface in advanced hydraulic circuits where precise metering and repeatable performance are essential.
