1. EZ-C should not be used in flow down service including on-off applications.
2. Pressu re drop cannot exceed maximum inlet pressure as indicated in the specification table on page 2.
3. Pressure drops at intermediate temperatures may be interpolated.
* Pressure drops are in excess of CL600 pressure ratings per ASME B16.34 for CF8M b o d y material.
