Overview
The VF1430570-831.875 attemperator valve plug is a critical control component for industrial steam systems. Sized at 1-1/2″ for standard industrial piping, this valve plug regulates the flow and temperature of steam in boiler feedwater, HRSG (heat recovery steam generator), and power plant applications. The attemperator function integrates spray water injection or steam path control to maintain precise outlet temperatures and protect downstream equipment from thermal stress.
