In addition, Type R622 regulators have internal relief
across the diaphragm to help minimize overpressure.
Any outlet pressure above the start -to -discharge point
of the non-adjustable relief valve spring moves the
diaphragm off of the relief valve seat, allowing excess
pressure to bleed out through the screened spring
case vent.
