Three Stage Nozzle-flapper Electro-Hydraulic Servo Valve

Product Description: The FF-791 series electro-hydraulic servo valve is an electric feedback three-stage nozzle baffle high flow servo valve. This type of servo valve uses a two-stage dual nozzle baffle servo valve as the pilot valve, with fast response and high dynamic performance. The LVDT valve core position sensor is used internally for position closed-loop control, resulting in small hysteresis, high resolution, and good repeatability accuracy. Compared to two-stage jet tube high flow servo valves, its dynamic response is higher. This series of three-stage servo valves features both high flow rate and high dynamic response.
