Product Introduction: It is a member of Moog’s D661 series servo proportional valves, which are electro-hydraulic control valves with excellent performance. The valve adopts a displacement sensor to provide point feedback on the position of the main valve core, and is equipped with a built-in electronic amplifier to perform closed-loop control on the main valve core, ensuring high control accuracy and stability. It can be widely used in various electro-hydraulic control systems that require precise flow and pressure control.
Technical Specifications: The maximum working pressure is 31.5 MPa. The flow control range is wide, and the specific flow value varies according to different working conditions. The frequency response range is 10 – 30 Hz, and the step response time is 2 – 45 ms. The installation bottom surface complies with the ISO 4401 standard. The valve body is made of high-quality materials to ensure its structural strength and corrosion resistance. The working temperature range is suitable for most industrial environments, generally between -40℃ and +135℃.
Functional Features: It has high control accuracy, and the displacement sensor and electronic amplifier form a closed-loop control system to effectively reduce the influence of external interference on the control effect. It has good dynamic response performance, can quickly respond to changes in input signals, and is suitable for occasions that require rapid adjustment of the hydraulic system. It has strong anti-pollution ability, and the built-in filter element can effectively prevent impurities in the hydraulic oil from entering the valve core and affecting the normal operation of the valve. The structure design is reasonable, which is convenient for installation, debugging, and maintenance.
Application Scenarios: It is applicable to high-frequency response hydraulic control systems, such as precision machine tools, where it can control the movement accuracy of the machine tool spindle and feed mechanism. It is also used in plastic machinery, such as injection molding machines, to control the injection speed and pressure, improving the quality of plastic products. In addition, it can be applied to the control systems of construction machinery and aerospace equipment to ensure the stable and reliable operation of the equipment.
