The overload problem of the electric butterfly valve is very clear to everyone. There are two main types of the main engine of the electric butterfly valve, namely, with and without a thrust disc. What is the difference between the two? One can output torque directly, and the other cannot. It needs some media to complete the conversion. In the production process, the motor can not meet the use requirements. Once the overload problem occurs, we need to find the reason immediately. The first case is that the voltage of the power supply is too low, and the motor cannot obtain the required torque, so it is easy to be in the load state, and the electric butterfly valve will stop running. In the second case, the previously set torque is already greater than the stop torque, and excessive torque will continue to be generated in the production process, and the motor will be forced to stop. It is also convenient to prescribe the right medicine for these two cases.

Pneumatic three-way regulating valve: this type of regulating valve is suitable for the equipment where one fluid flows through it in two ways or combines two fluids into one fluid;
