Note:
1. The torque value is calculated based on a normal temperature.
2.The torque value is calculated based on the design pressure under full differential pressure.
3. The seat is RPTFE for classes 150–900 and PEEK for classes 1500 and 2500.
4. The torque shown in this table is to be used as a guide for actuator selection. A safety factor of 1.3~1.5 is recommended for actuator sizing.
