Apr 27, 2023 · Valves have a unique ability to control fluid within a hydraulic system. com/c/upmation/joinRead the full blog post at https://upmation. Directional control valves perform only three functions: change direction of fluid flow. Unlike the cylinder, the motor rotates continuously and does not force the fluid over the pressure relief valve. Basic check valves allow fluid to flow in one direction but prevent fluid from flowing in the opposite direction. They are used to start, stop, slow, accelerate, and change the direction of motion in a cylinder. Learn more about their design, operating principle, and types. Directional control valves can be classified according to- type of spool. S. These three functions usually operate in combination.
