Built with Woodward’s industrial-grade materials, the 9905-860 features a corrosion-resistant alloy housing, high-temperature-resistant coil windings (suitable for -40°C to 135°C operating temperatures), and low-permeation internal seals. 

These components enable the solenoid to resist harsh conditions such as engine vibration, hydraulic fluid contamination, and extreme temperature fluctuations, maintaining consistent performance over long service cycles.

As a key component in Woodward’s power control ecosystem, it is primarily used to regulate hydraulic pressure or fluid flow in diesel/gas engine governors, turbine control systems, and construction machinery hydraulic units. 

Core specifications include: 24V DC rated voltage, normally closed (NC) configuration, direct-acting actuation (no external pilot pressure required), compact structure for easy installation, 

and compliance with international standards (e.g., ISO 5598 for hydraulic solenoid valves and SAE J1171 for electrical safety in automotive/industrial applications).

伍德沃德（Woodward）9905-860 是一款高可靠性直动式液压控制电磁阀，专为工业动力系统、发动机控制单元及重型液压执行回路中的精准流体调节场景设计。

该产品额定供电为 24 伏直流（24V DC），采用 “常闭型”（NC）工作模式 —— 断电时保持关闭状态，阻断液压油流通；接收到稳定电信号后立即开启，可在对响应速度要求严苛的场景中实现快速反应与精准控制。

作为伍德沃德动力控制系统生态中的关键部件，其主要用途是调节柴油 / 燃气发动机调速器、涡轮控制系统及工程机械液压单元中的液压压力或流体流量，保障动力设备的平稳运行与精准控制。

核心技术参数包括：额定电压 24 伏直流、常闭（NC）结构、直动式驱动（无需外部先导压力）、紧凑型设计便于安装，且符合国际标准（如液压电磁阀相关的 ISO 5598 标准、汽车及工业电气安全相关的 SAE J1171 标准）。
