identification of the parts, see the Parts List
1. Nitrile O-rings are used in optional top-mounted handwheel, adjustable down travel stop, and adjustable up travel stop assemblies.
2. Use this value to determine the maximum torque output allowed.
3. The pressure / temperature limits in this manual and any applicable standard or code limitation for valve should not be exceeded.
4. Exceeding any torque requirements could damage the actuator and impair safe operation.
