Notes:
1.The above table is for TF & TT series valves, which are with ISO 5211 mounting flange and adaptablity for all types actuators mounting.
2.The torque value showed in above table is the valve torque at normal temperature. For customer's sizing actuator:
a. If medium temperature is -10℃~40℃, the output torque of actuator should be 1.5 times the valve torque;
b. If medium temperature is less than -10℃, the output torque of actuator should be 2 or 2.5 times the valve torque
