Modulating control valves are advanced automated devices designed for precise flow regulation in systems or processes. Unlike simple on/off valves, they allow accurate control of flow rates through feedback and control signals managed by actuators. Available in two main types—rising stem and quarter-turn—these valves are controlled by electronic or mechanical actuators that adjust the valve's position to maintain a desired flow rate. They are essential in applications requiring detailed control, such as temperature regulation and pressure management, making them ideal for systems that demand exact fluid flow control, including water, air, or steam.
