There are significant differences and respective advantages and disadvantages between electric ball valves and hand ball valves in several aspects. This article provides a detailed comparison between the two.
Electric Ball Valve: The switch operation is achieved through an electric actuator (such as an electric motor or solenoid valve), which allows for remote control and a high degree of automation.
Hand Ball Valve: The switch control is achieved by manually rotating or moving the handle, relying on direct manual operation.
Electric Ball Valve: High degree of automation, can be linked with other automatic control devices (such as PLC), enabling automated control, improving production efficiency and precision.
Hand Ball Valve: Low degree of automation, entirely dependent on manual operation, unable to achieve automated control.
Electric Ball Valve: Suitable for situations requiring frequent switching or remote control, such as large industrial systems, water treatment equipment, etc. Its operation is convenient and can achieve long-distance and automated control.
Hand Ball Valve: Suitable for simple pipeline control systems, such as small water pumps, household heating systems, etc. In these scenarios, hand ball valves can meet basic switch control needs, and are simple to operate and cost-effective.
Electric Ball Valve:
Compact structure, reliable sealing, and easy maintenance.
The sealing surface and the ball surface are often in a closed state, less likely to be eroded by the medium.
Large flow capacity, low flow resistance coefficient, resulting in more precise and stable fluid control.
Equipped with a locking hole to prevent unauthorized operation.
Hand Ball Valve:
Simple structure, small size, and light weight.
Tight and reliable, with good sealing performance, and widely used in vacuum systems.
Convenient operation, quick switching, only needing to rotate 90° from fully open to fully closed, facilitating long-distance control.
Easy maintenance, as the sealing ring is generally movable, making disassembly and replacement relatively easy.
Electric Ball Valve: Due to its higher degree of automation and more complex structure, its price is relatively higher compared to hand ball valves. Moreover, the installation and maintenance of electric valves require more specialized skills and tools, thus the overall cost is also higher. However, the high degree of automation can reduce the need for manual intervention and the likelihood of human error, thereby lowering long-term maintenance costs.
Hand Ball Valve: The manufacturing cost is relatively low, and installation and maintenance are relatively simple, resulting in a lower overall cost. However, it may require more frequent manual maintenance and operation.
Electric Ball Valve: In scenarios with high safety requirements, such as in the petroleum, chemical industries, choosing an electric ball valve with safety erosion functions and fireproof measures may be more appropriate.
Hand Ball Valve: Although the ease of operation is relatively lower, it generally also has basic safety features, such as designs to prevent unauthorized operation.
In conclusion, there are significant differences and respective advantages and disadvantages between electric ball valves and hand ball valves in several aspects. The choice of which type of ball valve to use depends on the specific application scenario and requirements. If automated control and remote control are needed, and the budget allows, then choosing an electric ball valve is more appropriate; if only simple switch control is required and the budget is limited, then choosing a hand ball valve is more economical and practical.
