Features:
bronze butterfly valve offer excellent corrosion resistance, resisting attack by acids, alkalis, and other chemicals, ensuring long-term reliable operation in relatively harsh operating environments, such as those found in the chemical, petroleum, and pharmaceutical industries. Copper valves also effectively prevent rust and corrosion, ensuring water quality remains uncontaminated, making them suitable for small water supply systems with high water quality requirements.
bronze butterfly valve thermal expansion coefficient closely matches the temperature fluctuations of the fluid, reducing thermal stress on the valve during temperature fluctuations and extending its service life. Furthermore, copper's high toughness allows it to deform under external forces such as impact and extrusion without cracking, making it suitable for applications requiring resistance to external forces.
