Moog D635‑606C Hydraulic Servo Valve (Framo P/N A11592) is a high-performance, factory-new servo valve tailored for precision control in marine and offshore hydraulic systems. Engineered to meet Framo specifications, this valve delivers exceptional performance in critical applications such as cargo and ballast pump modulation, trim systems, and hydraulic positioning. Featuring refined spool mechanics and rugged construction, the valve achieves superior linearity, rapid response, and reliable operation under demanding conditions.
At its core, the D635‑606C employs Moog’s advanced proportional spool technology, featuring a precision-machined spool and sleeve assembly within a hardened aluminum housing. The valve responds efficiently to electrical input signals, enabling fine-grained control over flow and pressure at rated pressures up to 350 bar. Its optimized flow paths minimize pressure loss and internal leakage, delivering consistent volumetric efficiency and quiet operation—even in high-frequency duty cycles.
Robust materials and manufacturing processes enhance durability and endurance. The valve’s body is treated for corrosion resistance, while internal components—including spool, springs, and armature—are manufactured to tight tolerances to ensure repeatability across millions of cycles. Electrical connectors meet marine-grade sealing standards and support seamless integration into existing Framo control architectures. The unit also features built-in damping to reduce hydraulic shocks and maintain system stability.
This Moog valve is ideal for retrofit or new-build installations, offering plug-and-play compatibility with Framo systems due to its exact hydraulic porting, electrical interface, and mounting pattern. It enables engineers to implement high-precision servo control with minimal adaptation effort. In sum, the Moog D635‑606C (Framo P/N A11592) Hydraulic Servo Valve delivers unmatched accuracy, durability, and integration ease—providing a reliable solution for demanding hydraulic control in marine and industrial environments.
