Note:
1. The data provided in the table represents the standard factory configuration for our product, assuring quality and consistency.
2. Please note, the rated torque is calibrated to be 0.75 times the maximum torque, optimizing performance.
3. The specified working time is based on 50Hz; for 60Hz, simply multiply by 5/6 of the 50Hz working time. The maximum torque remains unchanged.
4. For custom sizing to meet your specific valve stem requirements, please reach out to our sales team.
