1. Manual operation: The manual operation of flange ball valves usually adopts a structure such as a handle or handwheel, and the opening and closing degree of the flange ball valve is controlled by manually rotating the handle or handwheel. The advantages of manual operation are simple structure, low cost, and easy manual control, but there are also disadvantages such as inconvenient operation and the need for manual monitoring.

2. Pneumatic drive: The pneumatic drive flange ball valve adopts a pneumatic device to control the opening and closing of the ball valve, which has the characteristics of fast switching speed, sensitive response, and compact structure. It is widely used in the control of media such as air and steam. But it also requires higher costs and maintenance requirements.
3. Electric drive: Electric drive flange ball valves usually adopt structures such as motors or solenoid valves, which can control the opening and closing degree of the ball valve through electrical signals. Electric drive has the characteristics of compact structure, fast response speed, high accuracy, and is suitable for application in environments such as high temperature, high pressure, and hazardous media. But it requires high cost and precision maintenance.
4. Hydraulic drive: Hydraulic drive flange ball valves usually use hydraulic devices to control the opening and closing of the ball valves, which can achieve high-strength control requirements such as high working pressure and large flow rate. Therefore, they are widely used in industrial applications. The advantages of hydraulic drive are smooth operation and rapid response, but it requires working media such as hydraulic oil, as well as high costs and complex facilities such as pipelines and oil circuits.
Different driving methods have different characteristics, scope of application, and cost requirements. It is necessary to choose a suitable driving method based on actual work needs, comprehensively consider its advantages and disadvantages, and pay attention to its use and maintenance essentials to avoid faults and risks caused by improper use.
