A pressure relief valve contains a poppet with a 4.20 cm2 area on which system pressure acts. During assembly a spring with spring constant of 3200 N/cm is installed in the valve to hold the poppet against its seat. In order to pass full pump flow through the valve at the PRV pressure setting, the poppet must move 0.3 cm from its fully closed position. What should be the initial compression of the spring in the PRV if the full pump flow pressure is to be 40% greater than the cracking pressure?
