Butterfly valves are widely used across various industries due to their simple structure, quick operation, low pressure loss, energy efficiency, and compact design. Below are their typical application scenarios:
1. Industrial Fluid Control
Chemical Industry: Used for flow regulation of corrosive media such as acid-base solutions and organic solvents (e.g., sulfur dioxide gas control in sulfuric acid production).
- Oil & Gas: employed in crude oil and natural gas pipelines for flow and pressure regulation to ensure pipeline safety.
- Power Industry: used in cooling water and steam systems of thermal power plants to prevent equipment overheating.
-
2. Water Treatment & Environmental Protection
- Water Supply & Drainage: flow control in urban water supply and wastewater treatment plants (e.g., pipeline isolation in sludge dewatering facilities).
- Flue Gas Treatment: regulates limestone slurry flow in desulfurization systems to improve environmental efficiency.
-
3. HVAC & Ventilation
- Central Air Conditioning: flow regulation in chilled water and hot water pipelines for precise temperature control.
Industrial Ventilation: airflow control in chemical plants and subway stations to ensure air quality.
4. Food & Pharmaceutical
- Sanitary Applications: with electropolished surfaces, suitable for sterile environments like beverage and pharmaceutical production (e.g., juice filling lines).
- Food Processing: controls flow of edible oil, milk, etc., ensuring product consistency.
5. Special Conditions
- High-Temperature & High-Pressure: metal-sealed butterfly valves are used in high-temperature gas or steam pipelines in metallurgy and power plants.
- Dusty Environments: pneumatic ventilation butterfly valves are used in boiler flues and dusty gas control, withstanding temperatures up to 300°C.Butterfly valves offer strong adaptability, and the final selection should consider medium characteristics, temperature/pressure requirements, and automation needs.
