Product Overview
The Woodward 8235-140 is a precision-engineered proportional solenoid valve designed for accurate electro-hydraulic control in demanding industrial applications. As part of Woodward’s renowned 8235 series, this valve utilizes a high-response proportional solenoid actuator coupled with a precision-machined spool and sleeve assembly to deliver infinitely variable flow and pressure control proportional to the electrical input signal. Unlike simple on/off directional valves, the 8235-140 enables smooth, stepless modulation of hydraulic actuators, making it ideal for closed-loop position, velocity, and force control systems. Its robust construction and precise metering characteristics ensure repeatable performance in the most rigorous industrial environments.
