Product Overview
▔▔
The Moog D765 series represents a high-performance, two-stage flow control servovalve engineered for precise electro-hydraulic motion and position control systems. Positioned within Moog's premium industrial valve lineup, the D765 series utilizes a mechanical feedback design driven by a robust torque motor and a nozzle-flapper pilot stage, translating electrical input signals into highly accurate, proportional hydraulic flow outputs.
Key Advantages
▔▔
- Series + Type + Core Function: D765 Series Two-Stage Mechanical Feedback Flow Control Servovalve designed for closed-loop industrial applications requiring rapid dynamic response and superior steady-state accuracy.
- High Dynamic Performance: Exceptional frequency response and minimal hysteresis ensure tight tracking capabilities in demanding closed-loop loops.
- Robust Construction: Designed to withstand harsh industrial environments while maintaining reliable operation under high continuous pressures.
- Precision Control: Exceptional resolution and repeatability make it ideal for high-precision load control, velocity regulation, and position feedback loops.
