Product Overview
Hydraulic servo valves are the core precision control components of electro-hydraulic servo systems, converting electrical signals into precise hydraulic flow and pressure outputs to enable closed-loop, high-precision continuous control of actuator position, speed, and force. Our portfolio includes nozzle-flapper, jet-pipe, and direct-drive servo valve types, offering fast response, high accuracy, minimal hysteresis, and superior resolution. Designed with strong interference resistance for demanding operating conditions, these valves are widely used in hydraulic test rigs, aerospace test equipment, material testing machines, precision metallurgical machinery, and advanced automated production lines requiring exceptional dynamic performance. We provide selection support, alternative solutions, and comprehensive technical services.
