Pump Control Valves are the main controller of system pipelines. They control the rate of flow, pressure in the system, and any potential pressure transient events. When a pump loses power and shuts down for a given period of time, kinetic energy is trapped inside the column of water. A pump control valve is put into the pipeline to prevent catastrophic system failure. There are various types of pump control valves for use in a wide range of applications and this presentation will explain them all.
