Output torque of double acting actuators 双作用气动执行器输出扭矩：

Torque table for double acting 双作用扭矩选型表:

Selection of double acting actuators:

The suggested safety factor for double acting actuators under normal working condition is 20%~30%, example:

● Torque of valve = 100Nm

● Torque of actuator = (1+30%)*100Nm=130Nm

● System pressure is 5Bar, then selected model is KPA-D160

 

双作用执行器选型：

一般情况下，双作用执行器安全系数为20%~30%，例如：

● 阀门扭矩 = 100Nm

● 执行器扭矩 = (1+30%)*100Nm=130Nm

● 如果系统压力为5Bar. 则选执行器型号为KPA-D160即可
