Finally, of course, the temperature of the working environment of the pneumatic control valve should be between - 30 ° C and 60 ° C, and the relative humidity should not exceed 95%. However, straight pipe sections are required at the front and back of the control valve, and their length should not be less than 10 times the pipe diameter, in case the straight pipe section of the valve is too short, which will eventually affect the flow characteristics. 　　　　

The power of the electric valve actuator is generally supplied by the motor, so it is necessary to master some common sense about the motor. In this way, we can find and eliminate the potential accident of motor on electric actuator as soon as possible, and ensure the safe operation of electric actuator and electric valve.
