Products 263 ASCO biodiesel combustion Emerson Series 262 UL valves

Emerson has launched its new ASCO series 262 and 263 biodiesel valves, said to be the first combustion valves certified for use with biodiesel blended fuel in industrial and commercial boilers in the Americas and Asia.

The biodiesel valves make it possible for district heating and commercial boiler burner applications to transition to a more sustainable energy source, the company says, simplifying compliance with evolving regulations while reducing boiler users’ greenhouse gas (GHG) emissions and carbon footprints.

Underwriters’ Laboratories (UL) recently updated its oil burner standard, UL 428B, to include biodiesel blends up to 20% (B20).

Series 262 and 263 valves feature an elastomer that is compatible with B20 and are certified under UL 428B.
