Flow Laboratory – Precision Testing for Optimal Process Control At FaraTose’e Daniel (Danielco), our state-of-the-art Flow Laboratory provides manufacturers with the means to verify the real-world performance of their products under dynamic process conditions. Unlike basic static testing, our facility operates in actual closed-loop control environments, delivering accurate, realistic, and actionable performance data. Why Closed-Loop Testing Matters Evaluating control valve assemblies under closed-loop conditions is the only true way to measure variability performance. Our testing process demonstrates how the right control valve choice can significantly reduce process variability—enhancing efficiency, reliability, and long-term operational stability.
