This situation is extremely destructive and may wear out the trim and body parts of a. Butterfly valves for cavitation service where line size doesn't allow use of sliding stem control valve (globe style) and ergonomics invariably permit use of only butterfly valves, i have found that except a. Vapor bubbles form if the liquid’s pressure falls to near the vapor pressure as the liquid passes through the control valve
What is Control Valve Cavitation ? | Cavitation Damage on Valves
Bubbles can suddenly collapse or implode.
A complete guide to causes, damage, and prevention
In this blog, we will delve deep into cavitation, flashing, and choked flow in control valves, explaining their causes, effects, and solutions for the oil & gas and process. Cavitation in control valves happens when liquid vaporizes in low‑pressure zones and the resulting vapor bubbles violently collapse, damaging. Cavitation is a common, yet potentially damaging, phenomenon in fluid system control valves It occurs when localized pressure drops below the vapor pressure of the liquid, forming vapor bubbles.
Learn the difference between flashing and cavitation in control valves, symptoms, damage risks, sizing data and valve selection fixes. Learn how cavitation happens in a control valve, its causes, damage effects, and proven prevention methods with real industrial examples and faqs.
