The G761-3003B is a model in the G761 and -761 series of servo valves manufactured by Moog. These servomotors are two-stage flow control mechanical feedback (MFB) servomotors using nozzle baffle pilot technology, providing high dynamics, high resolution and low hysteria. They are rugged in design to ensure long operating life, and have a compact design that takes up little space.

With flow ratings ranging from 0.5 to 75 L/min (0.125 to 19.5 GPM), the servo valves are suitable for electro-hydraulic position, speed, pressure or force control systems, as well as other systems requiring a high dynamic response. The spool is driven by a permanent magnet linear force motor that can flexibly drive the spool bidirectionally from the center of the spring pair. This design has advantages over proportional solenoid valves that can only produce one-way driving force.

Some of the key features of the G761-3003B include:
100% step response time: less than 4 to 16 milliseconds
Electrical parameters: Rated signal from 8 to 200 mA
Physical parameters: The mounting type is size 04 (ISO 10372-04-04-0-92) and weighs between 1.0 and 1.7 kg (2.2 and 3.8 lb)
In addition, the G761-3003B servo-valve offers additional options such as high zero bias, magnetic zero adjustment, breathable motor cover, special spinner valve sleeve (BSA) fit, internal parallel wiring, reverse polarity protection, ultra-high response, and more.
