Products Description

   The FF-106A series electro-hydraulic servo valve is a two-stage dual nozzle baffle flow servo valve with force feedback. Under a pressure difference of 21MPa, its flow range is 63L/min and 100L/min. This series of servo valves adopts a fully stainless steel shell, compact internal structure, high structural strength, and relatively small volume and weight. The installation direction of product plugs and sockets can be selected according to needs. It has the advantages of fast dynamic response, good linearity, zero drift, stable working performance, high reliability, long service life, small internal leakage, and low power consumption. The parameters of this servo valve are the same as those of FF-106, with a similar structure. An optional fifth oil supply port has been added on the basis of FF-106, and the hole spacing of the installation screw has been changed, allowing for separate oil supply to the pilot stage.
