MOOG D633-317B電源伺服閥
1.產 品 資 料 介 紹：
- 直動式 DDV + 電源集成架構：MOOG D633-317B 延續(xù) D633 系列經典直動式設計，由永磁線性力馬達直接驅動閥芯，同時內置集成化電源模塊，支持 18-32V DC 寬壓輸入，相比 D634-501A 的單一 24V 供電，電源適配性更靈活，可耐受工業(yè)電網 ±20% 電壓波動，適配冶金、石油化工等電壓不穩(wěn)定場景。
- 大功率線性力馬達設計：采用超大驅動力線性力馬達，輸出推力較 D634-501A 提升 40% 以上，可驅動更大口徑閥芯，配合一體化電源模塊的穩(wěn)定供電，即便在 35MPa 高壓工況下仍能保持閥芯運動平順性，避免因動力不足導致的控制滯后。
- 多油路兼容安裝結構：采用 ISO 4401 標準安裝底面，支持三通、四通及 2*2 通節(jié)流控制配置，油口連接可選 SAE 法蘭或 UNF 螺紋，相比 D634-501A 的標準化接口，更適配老舊液壓系統(tǒng)的改造需求，無需重新加工閥塊即可替換傳統(tǒng)伺服閥。
- 高壓大流量輸出特性：最大工作壓力達 35MPa（5000 psi），在 7MPa 閥壓降條件下額定流量覆蓋 30-80L/min，流量上限較 D634-501A 提升 33%，能為中型液壓執(zhí)行機構（如鑄造設備油缸、管道閥門驅動裝置）提供充足動力，適配高負載工業(yè)場景。
- 高頻響動態(tài)響應能力：頻率響應達 40-60Hz（±100% 輸入信號），100% 階躍響應時間≤15ms，雖略遜于 D634-501A 的 12ms，但在大流量輸出場景下動態(tài)性能優(yōu)勢顯著，可快速跟隨壓力調節(jié)指令，保障石油管道輸送系統(tǒng)的壓力穩(wěn)定性。
- 高精度閉環(huán)控制指標：通過 LVDT 閥芯位置傳感器實現(xiàn)電閉環(huán)控制，滯環(huán)誤差＜0.2%，分辨率＜0.1%，與 D634-501A 精度相當，但在高壓差（25-35MPa）工況下線性度更優(yōu)，誤差≤±1%，可滿足鑄造設備的精密流量控制需求。
MOOG D633-317B電源伺服閥 英文資料：
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.
