BFFW type valve is a direct acting proportional directional valve controlled by a proportional electromagnet with electric feedback, used to control the flow rate and direction of liquid flow. This valve has strong oil flow capacity, small hysteresis loop, high repeatability, and is suitable for closed-loop control circuits. It is widely used in automation control in various fields such as machine tools, light industry, metallurgy, mining, aerospace, etc.
