Moog D661-4013Servo Proportional Valve
- Product Introduction: It belongs to the D661 series of Moog. It is an electro-hydraulic conversion and power amplification component. It can convert small-power electrical signals into large-power hydraulic energy output, and is widely used in various electro-hydraulic control systems. The valve adopts advanced design and manufacturing processes, ensuring high performance and reliability.
- Technical Specifications: The flow range is 30-1500 l/min under a pressure drop of 1.0MPa. The maximum working pressure is 35.0MPa. The resolution is less than 0.2%. The hysteresis is less than 1.0%. The response time is 10-42ms. The weight is 5.6kg. The installation form complies with the ISO standard, with an additional T port of ISO 4401-05-05-0-05 type.
Detailed content
- Functional Features: It adopts a new type of Servo Jet pilot stage, which improves the dynamic characteristics of the entire valve. The large-flow internal flow channel design greatly increases the rated flow of the valve. The main spool position is electrically fed back by a displacement sensor, and the built-in electronic amplifier performs closed-loop control on the spool displacement. It has a Fail-Safe function, which can ensure that the machinery and equipment are in a safe position when an unexpected power failure occurs.
- Application Scenarios: It is suitable for electro-hydraulic position, speed, pressure, or electro-hydraulic control systems, and other control occasions that require high dynamic response. It is widely used in industrial fields such as metallurgy, electric power, and machine tools. For example, in the rolling process of metallurgical equipment, it controls the position and speed of the rolling mill to ensure the quality of the rolled material. In the power generation process of power plants, it participates in the control of turbine speed and load.
