Product Introduction: This servo valve is part of Moog’s G761 series, designed for medium-flow applications requiring high dynamic response. It uses a 2-stage design with a double-nozzle pilot stage and mechanical feedback, ensuring precise control of hydraulic flow. The valve is built to withstand harsh industrial environments, with corrosion-resistant materials and robust seals.
Technical Specifications: The rated flow rate is 10–63 l/min (2.6–16.6 gpm) at a pressure drop of 35 bar (500 psi). The maximum operating pressure is 315 bar (4,500 psi). It accepts input signals of 8–200 mA and operates on a 24 VDC power supply. The step response time is 6–12 ms, with a frequency response of 100–200 Hz for rapid system adjustments.
Functional Features: Mechanical feedback via a feedback wire ensures stable spool positioning, with hysteresis <0.5% for accurate control. The double-nozzle pilot stage minimizes friction, improving resolution and reducing wear. The valve’s compact design allows installation in space-constrained systems, such as industrial robots and medical equipment. It is compatible with a range of hydraulic fluids, including fire-resistant esters, for use in hazardous environments.
Application Scenarios: Used in textile machinery to control yarn tension, ensuring uniform fabric quality. In medical imaging equipment, it regulates hydraulic actuators for precise positioning of scanning components. It also controls the flow in hydraulic power units for plastic injection molding, maintaining consistent pressure during the injection cycle.
