1. Compare table value with torque requirements of the valve plus the torque required to compress the power actuator spring (from Fisher C atalog 14). Note that dynamic torque of the valve
may have a positive or negative effect on total torque required.
2. Has spur gear.
3. 2A 3/4 inch shaft will also mount on the 1061 size 40, 60, and 68.
4. Maximum torque of connection between power and manual actuator.
