G771K203A is a servo control valve produced by MOOG Company, belonging to the G77X/-77X series of flow control servo valves. Here are some key information about the servo valve:

The output stage of the valve is a closed center, four-way slide valve. The pilot stage is a symmetrical dual nozzles and baffles driven by a dual air gap, dry torque motor. Mechanical feedback to the slide valve position is provided by the cantilever spring, and the valve design is simple yet robust, ensuring reliable, long-life operation.

These valves are suitable for electro-hydraulic position, speed, pressure or force control systems with high dynamic response requirements. The G77X/-77X series is ideal for applications that require exceptional dynamic performance.

The valves are available in intrinsically safe versions for applications in potentially hazardous environments, with specific models certified to FM, ATEX, CSA, TllS and IECEx standards.

The G77X/-77X series is a proven technology for reliable operation in machines that require high performance, stability and accuracy. Moog's mechanical feedback valves are designed to provide high reliability and long service life.

Flow ratings range from 1.9 to 57 L/min (0.5 to 15 gal/min), with options of 4, 10, 19, 38, 57 L/min (1, 2.5, 5, 10, 15 gal/min) available as standard.

Maximum working pressure is 210 or 350 bar (3,000 or 5,000 psi).

The 100% step response time is 4 to 17 milliseconds and the frequency response is 115 to 215 Hz.

Signals are rated from 8 to 200 mA, with 8, 15, 20, 40, 200 mA options available as standard.
