2025-07-09 You will find the best valve choice depends on your specific application. Diaphragm valves work well when you need precise control, cleanliness, or resistance to corrosive media. Ball valves handle high-flow and high-pressure tasks, offering quick shutoff and durability. Engineers often focus on valve size, pressure rating, and flow coefficient (Cv) to match performance needs. Correct sizing prevents issues like poor control and instability, making it important to select diaphragm valves or ball valves based on your process demands.
