Safety Shutoff Valve

Emerson has launched its ASCO Series 262 and 263 Biodiesel Valves, the first certified for use with biodiesel blended fuel in industrial and commercial boilers in the Americas and Asia, the company says. Biodiesel fuel can reduce GHGs from 50% to 86% but is a corrosive medium that requires specially designed and certified products. 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. A full selection of explosion-proof enclosures is also available.
