1. Compare table value with torque requirements of the valve plus the torque required to compress the power actuator spring (from Fisher Catalog 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.
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
