Relevant information What are the precautions for the use and operation of pneumatic high-pressure ball valves What are the advantages of pneumatic high-pressure ball valves How to operate electric butterfly valves What are the characteristics of electric three-way ball valves What are the characteristics and functions of pneumatic high-pressure ball valves

3. The output torque and speed output torque value of the electric device is one of the important technical parameters of the electric device, and also an important parameter to be selected in use. If the output torque of the electric device selected when assembling the electric valve is too large or insufficient, it is not advisable. In general, the electric device manufacturer needs to test and adjust the output torque value when the product leaves the factory, which is relatively accurate. If excessive output torque margin is selected, the electric valve will have great potential danger. Once control and protection failure occurs, it will easily cause valve damage (valve stem bending, valve body cracking) and pipeline system accidents. Therefore, it is not advisable to select too large output torque margin. If the valve cannot be opened in actual work, it is also unreasonable.
