How come after the pressure of an SRH4000 is set, the pressure on the outlet side increases slightly over time?

For ordinary regulators, including those of the SRH series, leakage cannot be completely prevented from the inlet side to the outlet side of the main valve due to the product’s construction. If consumption on the outlet side stops for a long time, the pressure on the outlet side may gradually increase. Consider installing a pressure relief valve, etc., as necessary.
Note) Even if the regulator has a relief mechanism, there is a slight difference between the relief start pressure and the set pressure, so the pressure may increase by that difference.
