Woodward 9907-1213 is a high-performance direct-acting solenoid valve designed for precise fluid control in industrial automation, power generation, and heavy-duty machinery systems. Operating on a 24V DC power supply, 

this valve features a "normally closed" (NC) configuration—meaning it remains closed to fluid flow when de-energized, and opens only when an electrical signal is applied, ensuring reliable shut-off and safety in critical applications.

Constructed with durable materials (including corrosion-resistant housing and high-grade internal seals), the 9907-1213 offers excellent resistance to harsh operating environments (e.g., temperature fluctuations, vibration, and industrial contaminants), 

maintaining stable performance over long service life. It is typically used to control the flow of hydraulic oil, fuel, or other compatible fluids in Woodward-manufactured control systems, such as engine governors, turbine controls, and hydraulic actuation units.

Key specifications include: 24V DC rated voltage, normally closed operation, direct-acting actuation (no pilot pressure required), 

compact design for easy integration into existing systems, and compliance with industrial safety standards (e.g., ISO 4413 for hydraulic fluid power systems).

伍德沃德（Woodward）9907-1213 是一款高性能直动式电磁阀，专为工业自动化、发电及重型机械设备系统中的精准流体控制场景设计。

该电磁阀采用 24 伏直流（24V DC）供电，配置为 “常闭型”（NC）—— 即断电时保持关闭状态，阻断流体流通；仅在接入电信号时开启，确保关键应用场景下的可靠截止与安全防护。

产品采用耐用材质制造（含耐腐蚀外壳及高等级内部密封件），可耐受恶劣工况（如温度波动、振动、工业污染物），在长期使用中保持稳定性能，适用于对设备可靠性要求较高的场景。

其主要功能是控制液压油、燃油或其他兼容流体的流量，常见于伍德沃德控制系统（如发动机调速器、涡轮控制器、液压执行单元）中，实现流体回路的精准通断控制。
