MOOG G631伺服閥 英文資料：
1、 Infrastructure and Design Characteristics
Two stage electro-hydraulic amplification architecture: Moog G631 adopts a two-stage design combining a pilot stage and an output stage. The pilot stage is driven by a dry torque motor to form a dual nozzle baffle valve, which enhances response sensitivity through a low friction structure; The output stage is a four-way slide valve, which uses a cantilever spring rod to achieve mechanical feedback of the valve core position. Compared with the direct acting design, it has more control stability in high flow scenarios.
Standardized integrated design: The installation bottom meets the ISO 4401 standard and can directly adapt to the standardized valve block interface of industrial equipment. Some models offer a fifth oil port option and support independent pilot oil source control, flexibly meeting the integration needs of different hydraulic systems and reducing modification costs.
Maintenance friendly structure: The pilot valve is equipped with a disc filter that can be replaced on site, and the filter element maintenance can be completed without disassembling the valve body, reducing the risk of failure caused by hydraulic oil pollution; The valve core and valve sleeve adopt precision matching technology, with strong component interchangeability, which shortens the downtime for maintenance.
2、 Core performance and control accuracy
Wide range pressure and flow adaptation: The maximum working pressure of the oil supply port can reach 31.5MPa (some models support 35MPa), and the rated flow rate covers 3.8-76L/min under a pressure ｄｒｏｐ of 7MPa. The maximum flow rate can reach 150L/min, which can match the multi power requirements from precision testing equipment to heavy-duty hydraulic actuators.
High dynamic response characteristics: The 100% step response time is only 10-15ms (under 210bar operating conditions), and the frequency response reaches 40-60Hz. The low friction design of the dry torque motor greatly reduces signal lag and can quickly adjust the flow rate according to instructions, adapting to high-speed motion control scenarios.
High precision control indicators: hysteresis error less than 0.5%, resolution better than 0.1%, mechanical feedback closed-loop ensures accurate correspondence between valve core displacement and input current, and micrometer level adjustment accuracy can be achieved in pressure and speed closed-loop control systems.
3、 Adaptability and System Collaboration
Precise matching of servo amplifier: It needs to be used in conjunction with an external servo amplifier to adapt to ± 15mA or ± 50mA rated control signals. It is highly compatible with the current output characteristics of amplifiers such as Moog 0062 series, and further improves the overall accuracy of the system through PWM drive and dual closed-loop control of the amplifier.
Endurance to harsh environments: The oil and environmental temperature can adapt to a wide range of -29 ℃ to 135 ℃. The valve body is made of high-strength alloy material, which can resist vibration, impact, and hydraulic oil pollution, and is suitable for harsh working conditions such as aerospace test benches and automotive manufacturing.
