Back to the point, for which I should have been more clear, was specifically for dual solenoid valves. You can buy a spring centered dual solenoid valves (mono stable). If you use one in FRC, the center section would have to be able to vent the discharge ports when system pressure is released. The spring return single solenoid valves also has to be able to vent the discharge ports when pressure is released. Not all do. All of this is not really relevant to what is essentially a control question. I generally prefer the single solenoid valves because they take one less output to do mostly the same thing.
