Products Description
The FF-101 series electro-hydraulic servo valve is a dual nozzle baffle force feedback electro-hydraulic flow servo valve, with a flow range of 1L/min to 8L/min under a pressure ｄｒｏｐ of 21MPa. At the same time, products with flow rates ranging from 10L/min to 16L/min can be customized according to user needs.
This series of servo valves adopts a stainless steel shell with high structural strength, no valve sleeve inside, and a simple structure. It has a compact structure, light weight, high dynamic response, stable and reliable operation, and long lifespan. Very suitable for hydraulic control systems with strict volume and weight requirements or low flow rates, such as robot control systems and small hydraulic equipment.
●The lead wire can be selected in both "P" and "R" directions
