MOOG D633-317B电源伺服阀
1.产 品 资 料 介 绍：
- 直动式 DDV + 电源集成架构：MOOG D633-317B 延续 D633 系列经典直动式设计，由永磁线性力马达直接驱动阀芯，同时内置集成化电源模块，支持 18-32V DC 宽压输入，相比 D634-501A 的单一 24V 供电，电源适配性更灵活，可耐受工业电网 ±20% 电压波动，适配冶金、石油化工等电压不稳定场景。
- 大功率线性力马达设计：采用超大驱动力线性力马达，输出推力较 D634-501A 提升 40% 以上，可驱动更大口径阀芯，配合一体化电源模块的稳定供电，即便在 35MPa 高压工况下仍能保持阀芯运动平顺性，避免因动力不足导致的控制滞后。
- 多油路兼容安装结构：采用 ISO 4401 标准安装底面，支持三通、四通及 2*2 通节流控制配置，油口连接可选 SAE 法兰或 UNF 螺纹，相比 D634-501A 的标准化接口，更适配老旧液压系统的改造需求，无需重新加工阀块即可替换传统伺服阀。
- 高压大流量输出特性：最大工作压力达 35MPa（5000 psi），在 7MPa 阀压降条件下额定流量覆盖 30-80L/min，流量上限较 D634-501A 提升 33%，能为中型液压执行机构（如铸造设备油缸、管道阀门驱动装置）提供充足动力，适配高负载工业场景。
- 高频响动态响应能力：频率响应达 40-60Hz（±100% 输入信号），100% 阶跃响应时间≤15ms，虽略逊于 D634-501A 的 12ms，但在大流量输出场景下动态性能优势显著，可快速跟随压力调节指令，保障石油管道输送系统的压力稳定性。
- 高精度闭环控制指标：通过 LVDT 阀芯位置传感器实现电闭环控制，滞环误差＜0.2%，分辨率＜0.1%，与 D634-501A 精度相当，但在高压差（25-35MPa）工况下线性度更优，误差≤±1%，可满足铸造设备的精密流量控制需求。

1、 Infrastructure and power adaptation characteristics
Direct acting DDV+power integration architecture: MOOG D633-317B continues the classic direct acting design of the D633 series, with a permanent magnet linear force motor directly driving the valve core. It also has an integrated power module that supports 18-32V DC wide voltage input. Compared to the single 24V power supply of D634-501A, the power supply is more flexible and can withstand ± 20% voltage fluctuations in industrial power grids, suitable for voltage instability scenarios such as metallurgy and petrochemicals.
High power linear force motor design: Adopting a super large driving force linear force motor, the output thrust is increased by more than 40% compared to D634-501A, which can drive larger diameter valve cores. With the stable power supply of the integrated power module, even under high pressure conditions of 35MPa, the smooth movement of the valve core can be maintained, avoiding control lag caused by insufficient power.
Multi oil compatible installation structure: Adopting ISO 4401 standard installation bottom, supporting three-way, four-way, and 2 * 2-way throttling control configurations, the oil port connection can be selected with SAE flange or UNF thread. Compared with the standardized interface of D634-501A, it is more suitable for the renovation needs of old hydraulic systems and can ｒｅｐｌａｃｅ traditional servo valves without reworking the valve block.
2、 Core performance and control accuracy
High pressure and high flow output characteristics: The maximum working pressure reaches 35MPa (5000 psi), and the rated flow covers 30-80L/min under 7MPa valve pressure ｄｒｏｐ conditions. The upper limit of flow is 33% higher than D634-501A, which can provide sufficient power for medium-sized hydraulic actuators (such as casting equipment oil cylinders and pipeline valve drive devices) and is suitable for high load industrial scenarios.
High frequency dynamic response capability: The frequency response reaches 40-60Hz (± 100% input signal), and the 100% step response time is ≤ 15ms. Although slightly inferior to the 12ms of D634-501A, it has significant advantages in dynamic performance in high flow output scenarios, and can quickly follow pressure regulation instructions to ensure the pressure stability of the oil pipeline transportation system.
High precision closed-loop control indicators: achieved through LVDT valve core position sensor for electric closed-loop control, hysteresis error<0.2%, resolution<0.1%, comparable to D634-501A accuracy, but with better linearity under high pressure difference (25-35MPa) conditions, error ≤ ± 1%, which can meet the precision flow control requirements of casting equipment.
