1.How does cracking pressure percentage change as the maximum pressure setting of the relief valve increases? Why?
2.Explain the term pressure override as it relates to pressure control valves.
3.Why is an understanding of the concepts of cracking pressure and pressure override important when selecting and installing a relief valve in a hydraulic system?
4.How do the concepts of cracking pressure, pressure override and full-flow pressure relate to the operation of other control valves, such as sequence and counterbalance valves?
