Note:
1. The data presented in the table reflects the standard factory configuration of the product.
2. The rated torque is calculated as 0.75 times the maximum torque, offering a reliable performance benchmark.
3. The working time listed is based on 50Hz; for 60Hz, multiply by 5/6 to adjust working times accordingly while maintaining maximum torque consistency.
4. For customization inquiries regarding valve stem sizes, please reach out to our dedicated sales team.
