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 271 N
S
m (2400
inch-pounds) for the size 0-KE actuator, 678 N
S
m (6000 inch-pounds) for the size 2-KE actuator, 1360 N
S
m (12,000 inch-pounds) for the size 6-KE actuator, 2260 N
S
m (20,000
inch-pounds) for the size 7-KE actuator, 3390 N
S
m (30,000 inch-pounds) for the size 9-KE actuator, and 6780 N
S
m (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.
