1. For Types MR95LD and MR95HD regulators, the pressure ranges indicate the differential pressure that can be obtained with the indicated spring. The differential pressure (spring
setting) is added to the spring case loading pressure to determine the actual outlet pressure.
2. Springs meet NACE MR0175-2002 and NACE MR0103 requirements only for applications in which the spring is not exposed to the sour gas.
