Two-stage Jet Pipe Servo Valves and Three-stage Nozzle Flapper Servo Valves of the FF-792 Series

The FF-792 series electro-hydraulic servo valves are electro-feedback three-stage nozzle flapper high-flow servo valves. Under a pressure difference of 7MPa, their flow rates are 400L/min, 630L/min, 800L/min, and 1000L/min. This type of servo valve uses a two-stage double-nozzle flapper servo valve as the pilot valve, featuring fast response and high dynamics. The product internally adopts an LVDT spool position sensor for position closed-loop control, thus having small hysteresis, high resolution, and good repeatability. Compared with two-stage jet pipe soil flow servo valves, it has a higher dynamic response. This series of three-stage servo valves also has the characteristics of large flow rate and high dynamic response. The pilot stage can be optionally supplied with internal or external oil. The control box is designed with an external electrical zero adjustment device, making it more convenient to use. Meanwhile, according to requirements, the spool safety position after power failure or pressure failure can be customized. It is suitable for the iron and steel metallurgy industry, etc.
