Product Overview
The MOOG D633Z532B / R16KO1F0NSS2 is a high-performance direct drive servo valve from the MOOG D633 series, engineered for precision electrohydraulic control in demanding industrial and motion control systems. Utilizing MOOG’s advanced Direct Drive Valve (DDV) technology, this servo valve eliminates the need for a pilot stage by directly coupling a high-force linear force motor to the spool, resulting in exceptional dynamic response, high resolution, and superior contamination tolerance. The D633 series is a two-stage design with spool position feedback, delivering precise flow control proportional to the electrical input signal. With its robust construction and ISO 4401 mounting interface, this valve is ideally suited for closed-loop position, velocity, and force control applications where accuracy and repeatability are critical.
