The purpose of this study was to analyze the effect of waste valve and the delivery valve diameter on the 3-inch hydraulic ram efficiency. The waste valve is one important component of the hydraulic ram. The results showed that the diameter of the waste and delivery valves greatly affect the efficiency of hydraulic ram. The highest D’Aubuisson efficiency was 67.66% with the waste valve diameter of contained 2.75 inches and the in the waste valve variation of 2.75 inches diameter and delivery valve diameter of 2 2 inches. The lowest efficiency was 36.14% with the waste valve diameter of 2.25 inches and the delivery valve diameter of 0.6 inches.
