How much critical is molecular weight for pressure control valve
(OP)
I want to know how a PCV (Pressure control valve) works.
Only pressure matters regardless of flow? or the flow as well as gas density also matters?

Generally, if the pressure drop required increases, the port area needed to pass a fixed mass will decrease or at a fixed port opening, an increase in pressure drop will allow more mass to pass through it. However, if the pressure drop through the valve is more than 50% of the inlet pressure, then for a fixed port area, more pressure drop will not allow any more mass to to pass through the valve.
