Needle valves are designed for precise flow control in low-flow applications. They use a slender, tapered needle to regulate flow accurately. These valves are commonly used in instrumentation and pressure control systems. Needle valves allow gradual and controlled opening and closing. They are ideal for gases and liquids requiring fine adjustment. Their design supports high-pressure applications. Needle valves ensure stable flow and pressure regulation. They are widely used in laboratories and industrial monitoring systems.
