What does the âMOPDâ rating on solenoid valves mean? Solenoid valves are rated in terms of Maximum Operating Pressure Differential (MOPD). The MOPD rating for a valve is the maximum pressure differential against which the valve will reliably operate. For example, with the valve closed against an inlet pressure of 250 psi and an outlet pressure of 50 psi, the pressure differential across the valve is 250-50 or 200 psi. Emerson.
