The water and wastewater treatment industry depends on automated valve systems to regulate, control, and isolate fluid flow efficiently. Reliable valve automation ensures safe water distribution, wastewater processing, chemical dosing, and environmental compliance. Among the different valve types, ball valves and butterfly valves are widely used due to their versatility, durability, and ability to handle various flow conditions.
* Automated valves control water intake, treatment, filtration, chemical dosing, and discharge.
* Ball valves provide tight shut-off, while butterfly valves excel in large-diameter, high-flow applications.
* Ball valves are preferred for chemical dosing, while butterfly valves handle bulk flow regulation.
* Remote actuation ensures quick response to system fluctuations.
* Ball valves handle precise sampling, flushing, and chemical injection applications.
* Essential in industrial wastewater plants where hazardous chemicals are handled.
| Feature | Ball Valve | Butterfly Valve |
|---|---|---|
| Best For | Chemical dosing, small-diameter pipes, high-pressure shut-off | Large-diameter pipelines, bulk flow control |
| Functionality | On/Off isolation, throttling for precise control | On/Off, throttling for high-flow applications |
| Flow Characteristics | Full bore for minimal pressure drop | Moderate pressure drop due to disc in flow path |
| Durability | High resistance to chemicals and scaling | Lightweight, cost-effective, and easy to maintain |
| Common Applications | Chemical injection, filtration, pump isolation | Aeration tanks, sludge handling, high-volume water flow |
| Automation Suitability | Pneumatic, hydraulic, and electric actuation | Pneumatic and electric actuation |
* Best for butterfly valves in high-flow systems (e.g., aeration, sludge control).
* Used in remote locations for quick open/close response.
* Common for chemical dosing ball valves where fine control is needed.
* Ideal for remote monitoring in water treatment plants.
* Ball Valves: Used in chemical injection, backflow prevention, and sample collection.
* Butterfly Valves: Regulate large water flow in sedimentation tanks, filters, and reservoirs.
* Ball Valves: Handle sludge sampling, aeration control, and small-diameter pipelines.
* Butterfly Valves: Control effluent discharge, aeration, and bulk wastewater flow.
* Ball Valves: Used for precise chemical dosing in cooling towers and desalination plants.
* Butterfly Valves: Manage high-volume water movement in filtration and recycling systems.
