Product Introduction: The D760-866A is a high-performance servo valve designed for critical applications requiring exceptional control accuracy. It combines a two-stage design with mechanical feedback, converting electrical signals into precise hydraulic flow to drive actuators in demanding systems. Its robust construction ensures durability in harsh environments, making it suitable for industrial and aerospace applications.
Technical Specifications: The maximum operating pressure is 315 bar (4,500 psi). The rated flow is 4 to 63 l/min (1 to 16.5 gpm) at a 35 bar (500 psi) pressure drop per spool land. The frequency response ranges from 115 to 215 Hz, with a 100% step response time of 4 to 17 ms. It operates on a 24 VDC power supply and accepts input signals of 8 to 200 mA. The valve features a compact design with ISO 10372 mounting compatibility.
Functional Features: Utilizes a dual-nozzle flapper pilot stage for low friction, ensuring high resolution and minimal hysteresis. The mechanical feedback mechanism maintains spool position accuracy, even under fluctuating pressure. Its sturdy construction resists wear and contamination, extending service life. The valve’s high dynamic response allows for rapid adjustments, critical in applications requiring real-time control.
Application Scenarios: Ideal for aerospace test rigs, where it simulates flight loads on aircraft components. In industrial robotics, it controls joint movements for precise manipulation. It also regulates hydraulic pressure in metal extrusion presses, ensuring uniform material flow and product consistency.
