Product Details:

MOOG D633-333B-R16KO1F0NSS2 belongs to MOOG D633 series custom configured direct drive servo valve, adopting permanent magnet linear force motor structure and no pilot oil supply required. The suffix R16KO1F0NSS2 represents special customized electrical and spool configuration. Integrated built-in closed-loop spool position feedback electronics, it accepts analog command signal to adjust hydraulic flow precisely. The linear force motor directly drives the valve spool to achieve pressure-independent dynamic response and low power consumption at hydraulic null position. When power supply fails, the spool returns to spring-centered position for hydraulic equipment safety protection.

This custom servo valve delivers high resolution, low hysteresis and stable repeatability. MOOG D633-333B-R16KO1F0NSS2 direct drive servo valve is widely used in static and dynamic material fatigue testing machines, aerospace hydraulic simulation benches, metal forming presses and automated hydraulic manufacturing machinery. It can precisely control position, velocity and force of hydraulic actuators for high performance closed-loop hydraulic control systems.

Built-in internal filter reduces fluid contamination sensitivity. Every MOOG D633-333B-R16KO1F0NSS2 flow regulator undergoes complete factory performance tests before shipment, including flow characteristic curve test, frequency response test and internal leakage inspection. Strict quality control ensures stable and repeatable precision for closed-loop hydraulic control applications.
