    The minimum psi listed for the solenoid valves is minimum operating pressure differential, or in simpler terms the differential pressure required to overcome the internal spring on valve. Steam pressure would have to be over 5 psi on the inlet side and the outlet side would have to be at 0 psi. Depending on the type of steam system, this pressure may not be available..
