Technological Evolution of Intelligent Bronze Butterfly Valves (J-VALVES): Comparison between Electric Actuator And Manual Worm Gear Drive Schemes

Electric Actuator Drive

1.Operational Convenience
The J-VALVES BRONZE BUTTERFLY VALVES equipped with electric actuators are driven by electricity. Through control buttons or remote control systems, operations such as opening, closing, and adjusting the opening degree of the butterfly valve can be easily achieved. Operators don't need to directly touch the valve. This advantage is particularly evident in some complex environments or long-distance control .scenarios, greatly improving the operational efficiency.

2.Control Precision
It can achieve relatively precise control of the opening degree. The opening degree of the butterfly valve can be accurately adjusted according to the set angle values, and the error range is usually very small. This is crucial for some process links with strict requirements for flow control.

3.Automation Degree
It has a high level of automation and can be integrated with the entire industrial automation system. For example, it can be connected to a PLC control system and automatically execute the actions of the valve according to preset programs, adapting to the needs of modern intelligent production.

4.Applicable Scenarios
It is suitable for application in large industrial production lines, factories with a high degree of automation, and occasions that require remote control, such as chemical production workshops and large water supply and heating systems.

Manual Worm Gear Drive

1.Operational Convenience
If the J-VALVES BRONZE BUTTERFLY VALVE is driven by a manual worm gear, operators need to manually rotate the worm gear to operate the butterfly valve. In this way, it will consume relatively more physical strength and the operation speed will also be slower. However, in some small-scale places where the valve doesn't need to be operated frequently, it can also meet the basic requirements for opening, closing and adjusting.

2.Control Precision
Although the opening degree of the butterfly valve can be roughly controlled through manual adjustment, the precision is lower compared to that of the electric actuator. It is more difficult to achieve precise adjustment to a very small angle, and it mainly relies on the experience of operators to control.

3.Automation Degree
It basically has no automation ability and cannot automatically execute actions according to preset programs. It requires real-time manual operation. Therefore, its application in an automated production environment has certain limitations.

4.Applicable Scenarios
It is more suitable for some small-scale occasions with low requirements for automation and low operation frequencies, such as some small-scale civil pipeline systems and simple equipment matching pipelines.
