FLUID FLOW BASICS OF THROTTLING VALVES
www.controlglobal.comValves that are utilized as fluid control devices are typically “throttling valves”. Such valves experience internal velocity and internal pressure gradients (both positive and negative) that conclude with a permanent pressure loss (∆P) from the inlet pipe-to-outlet pipe connections. Throttling valve trim (plug-seat) experiences ...
