The Control Valve Characteristics Apparatus is designed to study the flow behavior and pressure-drop characteristics of different control valves such as globe, gate, and butterfly valves. It enables the plotting of valve flow curves and understanding of control response under various operating conditions. The equipment includes calibrated flow meters and precision valves for accurate experimentation. Ideal for engineering colleges, polytechnic institutes, and ITIs, this trainer helps students gain practical knowledge of process control in fluid systems and industrial flow regulation.
