Product Overview
The STAR HYDRAULICS 456-0075 is a high-performance electro-hydraulic servo valve engineered for precise, high-frequency control of hydraulic flow and pressure in demanding industrial motion-control systems. Manufactured by Star Hydraulics, a recognized name in precision fluid power components, this two-stage servo valve converts low-power electrical command signals into proportional hydraulic output through a torque-motor-driven pilot stage and a matched spool-and-sleeve second stage. The 456-0075 delivers exceptional resolution, minimal hysteresis, and fast dynamic response, making it the critical control element in closed-loop servo systems where position, velocity, or force must be regulated with repeatable accuracy. It is designed as a direct-fit replacement for OEM servo valve installations and is suited for continuous-duty operation in severe industrial environments.
