1. Values shown are the maximum allowable torque of a splined valve shaft except where indicated. Without regard to the shaft, maximum allowable torque output is 2400 inch-pounds for the

size 0-KE actuator, 6000 inch-pounds for the size 2-KE actuator, 12,000 inch-pounds for the size 6-KE actuator, 20,000 inch-pounds for the size 7-KE actuator, 30,000 inch-pounds for the size

9-KE actuator, and 60,000 inch-pounds for the size 10-KE:6 actuator.

2. Limited to this value by the maximum allowable output torque of the actuator.

3. Wheel-rim force required to produce maximum actuator output torque.

4. Handwheel is 152 mm (6-inch) diameter for keyed-shaft constructions.
