Cavitation Risks in Control Valves Cavitation in control valves can lead to serious damage not only to the valves themselves but also to the entire piping system. This damage is primarily due to vibrational noise energy, accelerated corrosion, and process contamination. The high noise levels associated with cavitation are caused by the formation and collapse of vapor bubbles near and downstream of the vena contracta. Susceptibility of Different Valves While cavitation typically occurs within the...

When gas or steam flows through a control valve, it generates noise, commonly referred to as "aerodynamic noise." Depending on the valve's size, flow rate, and the differential pressure across it, this noise can become loud enough to be irritating or even harmful to nearby workers. Understanding what causes aerodynamic noise and how to mitigate it is crucial for maintaining a safe and comfortable working environment. Figure 1. Velocity and Pressure Profile Inside a Control Valve...

The selection of pressure drop (Δp) for control valve sizing calculations is a critical aspect that is often misunderstood. It's essential to understand that Δp cannot be arbitrarily specified without considering the actual system in which the valve will be installed. Each component of the system, except for the control valve, has a fixed pressure loss at the required flow rate. This includes pipes, fittings, isolation valves, heat exchangers, and other process equipment. In contrast,...
