Pneumatic desulfurization butterfly valve Factory switching time Electric butterfly valve installed in front of or behind the water pump? 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.
、 Third, how to effectively repair when an error occurs. In case of any error or abnormality in the use of pneumatic butterfly valve, users should immediately stop the current operation and repair the butterfly valve accordingly. Generally, you can directly notify the manufacturer of the product to provide professional after-sales service. If you want to check, The corresponding operation can be carried out according to some basic steps of disassembly in the manual, so that you can check various problems that may occur in the butterfly valve more perfectly and formally, and you can also effectively try to solve them yourself, so that the butterfly valve can resume work more quickly. What are the important parameters of related electric butterfly valves? What are the differences between pneumatic butterfly valves and ordinary butterfly valves? What technology must be mastered to use pneumatic butterfly valve? Identify which commonly used pneumatic butterfly valve types are popular according to the five characteristics?
