Steam Control Valve Oversizing: Causes & Fixes | Vcore
Quick Summary: Steam control valve oversizing occurs when the selected flow capacity is excessive for the actual operating envelope. It can leave low-load operation close to the seat, where useful regulating travel is limited and small movements may produce disproportionate flow changes. Confirm minimum, normal and maximum steam flow with the corresponding pressures and temperatures, […]
