Siemens VKF41.150H Butterfly Valves for Burner FGR Hot Air

Description

Siemens VKF41… Butterfly Valves for Flow Control of Gases

The Siemens VKF… series butterfly valves are designed to control the flow of many common gases, they are used to throttle gases such as air, natural gas, or propane. These valves are wafer type, and mount between ANSI or DIN pipe flanges. Additional versions of the VKF…series butterfly valves are available for high-temperature or corrosive gas applications.

• VKF41…C standard butterfly valves control ambient temperature inert gases such as air, natural gas, or propane.
• VKF41…H high-temperature butterfly valves are typically used for FGR or hot air up to 550°F.
• VKF41…B biogas butterfly valves are typically used with corrosive gases such as digester gas. These valve bodies are electro-less nickel plated to prevent corrosion and wear caused by aggressive components of biogas such as hydrogen sulfide and ammonia.
