If LP = 90 psi, PP = 15 psi, CR = 0.4, what is the maximum pressure in the POC circuit?

Explanation:
In a pilot-operated control circuit, the maximum pressure in the POC path is found by adding a fraction of the pump pressure to the baseline load pressure. That fraction is the control ratio CR. Compute the additional pressure: CR times PP equals 0.4 × 15 psi = 6 psi. Add this to the load pressure: 90 psi + 6 psi = 96 psi. So, the maximum pressure in the POC circuit is 96 psi.
