Moog Servo Valve with 6-250m3 Drive Mode 5 Days Delivery and 1A Rated Current for Industrial Applications

An electrohydraulic servo valve is a precision component that acts as an interface between the electrical control system and the hydraulic power system. It receives a low-power electrical analog signal and converts it into a proportional, high-power hydraulic output (flow and pressure).

• First Stage: The torque motor deflects an armature and a flapper attached to it. This flapper moves between two nozzles, creating variable orifices that control the pressure on either end of the second-stage spool.
• Second Stage: The differential pressure moves the spool, which then controls the flow of hydraulic fluid to the actuator. A feedback spring creates a force that balances the input signal torque, ensuring precise spool positioning proportional to the electrical command.

• Filtration: Install a precision filter with a rating of 5 microns or less upstream of the servo valve.
• System Flushing: Before installing, thoroughly flush the entire hydraulic system to remove contaminants.
• Mounting: Can be mounted in any orientation with proper port alignments.
• Connections: Use O-ring seal connections and avoid welded fittings.

• Electrical Faults: Check supply voltage, cables, and connectors.
• Mechanical Failures: Inspect for stuck valve spool, damaged springs, or worn seals.
• Hydraulic Faults: Check for oil contamination, low oil level, or leaks.
• Valve Oscillation: May be caused by issues with resolution, valve port wear, or incorrect control parameters.
