In the process of processing, the use of machinery and equipment can improve the work efficiency, and it is inevitable that some failures will occur in the process of use. If the operators fail to grasp several troubleshooting methods, the use of machinery and equipment will be affected. Just like this electric butterfly valve, when using it, how many troubleshooting methods are there? 　　　　

What is the reason why the pneumatic ball valve can fill quickly? The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rolling torque. The completely equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium. It is generally believed that ball valves are most suitable for direct opening and closing. The main features of the ball valve are its compact structure, easy operation and maintenance, and suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
