The MOOG D634 is a direct-acting servo valve (DDV) launched by Moog Inc. It adopts a permanent magnet linear force motor to directly drive the valve core, featuring high dynamic response, pressure-independent operation, and large flow output. With a rated flow of up to 100 L/min and a maximum flow
The MOOG D660 series are high-performance proportional servo valves with integrated electronic components. Adopting jet pipe technology as the core design, they deliver excellent contamination resistance and superior dynamic response. They are widely used in industrial applications such as injection molding machines, die-casting machines, hydraulic presses, and metallurgical equipment. Radk
1. Overall Architecture The circuit adopts a differential operational amplifier M1 as the front stage. The command signal and system feedback signal are input via terminal 1, while terminal 2 serves as the balance input for zero adjustment. The difference signal is amplified and phase-inverted, then transmitted to the driver
