Additional Specifications
For casing pressure ranges and for material
identification of the parts, see the Parts List
1. Use this value to determine the maximum torque output allowed.
2. The pressure/temperature limits in this manual and any applicable standard or code limitation for valve should not be exceeded.
3. This maximum casing pressure is not to be used for normal operating pressure. Its purpose is to allow for typical regulator supply settings and/or relief valve tolerances.
