The relief valve is typically set at slightly higher than the cylinder working pressure. The hydraulic meter-in circuit is suitable for a positive resistance load such as hydraulic motor or hydraulic driven milling machine. We can use check valve and flow restrictor to reverse the cylinder but it can not control the return speed.
Working of hydraulic circuit for milling machine. Hydraulic circuit for milling machine is comparatively different from other circuits. Table movement of milling machine is required to be adjustable for different feeds for different type of work. Therefore for both strokes of the cylinder, on both ends of cylinder flow control valves are used.
