Hydrogen Valve Size Calculation

Post by iplikci52 »


I want to select a solenoid valve to control a fuel cell application. I know the upstream pressure and necessary gas flow. But I couldn't find how to calculate orifice size of the valve. Could you please help me?

I have two solenoid valves on the system. First one is inlet solenoid valve directly after regulator which regulates pressure of hydrogen to 5 psi. After inlet solenoid valve hydrogen flows through fuel cell stack and there is outlet solenoid valve after stack. Outlet solenoid valve is opening to air.

I want hydrogen flow of 216 slpm. What should be sizes of both solenoid valves? How can I calculate them?

Thanks for help.
