Prefill Valve is designed to be utilized in hydraulic systems for reducing the time needed for filling hydraulic cylinders. It is mostly utilized in double-acting hydraulic cylinders where the cylinder needs to be filled with fluid from both ends. It performs by pre-filling the cylinder with fluid from one end, while the other end is being filled. This reduces the times required for filling the cylinder, making the process of pre-filling more efficient. When the cylinder is pre-filled, it is allowing fluid for flowing to the other end of the cylinder, thus completing the filling process. Prefill Valve has usage in applications like construction and manufacturing.
