VKF41.200H Siemens Valve

Overview

The Siemens VKF41.200H is a high-temperature flanged butterfly valve specifically engineered for the control of hot air and flue gas in combustion systems. Designed as a wafer-style valve for mounting between counter-flanges, this 8-inch valve is built to withstand extreme thermal conditions while providing reliable throttling and shut-off in industrial burner applications.
