1. The internal relief performance values are obtained by removing the disk assembly. 2. For inlet pressure in excess of 1000 PSIG (69.0 BAR) refer to the maximum body and disk pressure ratings in the specifications section. 3. For pressure settings under 10 PSIG (0.69 BAR) inlet pressure should be limited to approximately 100 PSIG (6.90 BAR) so the set point adjustment can be obtained. 4. - Shaded areas indicate maximum inlet pressures allowed during system failure only.
