The method of checking and selecting electric butterfly valve device The electric butterfly valve device is also called electric actuator, which is an indispensable equipment for realizing remote control, automatic control and remote control of valves. Since the working characteristics and utilization rate of electric actuator depend on the type of valve, the working specifications of the device and the position of the valve on the pipeline or equipment, the correct selection of electric actuator is crucial to prevent overload. Generally, the correct selection method of electric actuator is as follows: operating torque Operating torque is the most important parameter for selecting electric actuator, and the output torque of electric actuator should be 1.3~1.5 times of the maximum operating torque of the valve.

What are the performance characteristics of pneumatic butterfly valve? The main feature of pneumatic butterfly valve is its small size and light weight. Its structure is relatively simple, and it is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is very convenient in the process of installation, disassembly and maintenance, which is also a major reason for its popularity.
