Description
Description:
Process butterfly valves are a popular choice for fluid control in numerous industries. These compact, quarter-turn valves employ a rotating disc to efficiently regulate fluid flow. Available in a range of sizes and materials, they are designed to withstand diverse process conditions and offer rapid operation and cost-effective solutions.
| Key Applications:
Water Treatment: Controlling the flow of water and chemicals. Oil and Gas: Regulating the flow of oil, gas, and other fluids. Chemical Processing: Controlling the flow of corrosive and hazardous chemicals. Food and Beverage: Controlling the flow of food products and beverages. Power Generation: Regulating the flow of steam and water. By understanding the different types and applications of process butterfly valves, you can select the right valve for your specific needs.
