Note:
1. The data presented in the table reflects the standard factory configuration of this exceptional product.
2. The actuator’s rated torque is ingeniously calibrated to 0.75 times of its maximum torque, optimizing performance.
3. The specified working time corresponds to 50Hz; for 60Hz operations, multiply by 5/6 of the 50Hz work time. The maximum torque remains consistent.
4. For bespoke sizes tailored to the valve stem, please reach out to our dedicated sales team.
