How a motorised actuator and shutoff valve solution improves safety and reliability in combustion systems
M
anufacturing giant Emerson has launched a new safety valve and motorised actuator
designed for industrial fuel oil burner recirculation and safety shutoff applications. Called the ASCO series 148/149, the solution provides a reliable, versatile tool for industrial users to help them prevent overpressure, leaks, and system malfunctions that can lead to health and safety incidents, according to the company. The valve is made from brass, the actuator, die-cast aluminum and the seal material is made from PTFE or polytetrafluoroethylene - a hydrophobic (water repellant) and low friction substance.
HIGH FLOW AND HIGH PRESSURE The product comes with one configuration suited to a wide range of combustion system applications and the valve and actuator are designed to be used together in one system for fuel oil recirculation as a safety shutoff. The combination comprises a
compact two- and three-way system with a motorised actuator that leads to rapid, reliable fuel line shutoff from an open to closed position in less than a second.
HIGH FLOW AND HIGH PRESSURE The system features a high flow

and high-pressure design that enhances heat output and meets approvals from UL (Underwriter Laboratories), FM (Factory Mutual) and CSA (Canadian Standards Association), it also improves fuel oil combustion system performance through higher pressure and media temperature tolerance.
ROBUST AND RELIABLE OPERATION The company has engineered the ASCO solution for robust and reliable operation in harsh outside environments, supporting an operating range from -40 degrees to 150 degrees Fahrenheit (-40 degrees to 66 degrees Celsius).
ALIGNING WITH INDUSTRY BEST PRACTICE “The ASCO Series 148/149 valve and actuator combination includes features that align with industry best practices such as redundancy, leak testing ports and overpressure protection,” said Ali Sarwar, global director of marketing, discrete automation, Emerson. “Safety being the highest priority, our new design strengthens the reliability of a critical piece of equipment found in burners and combustion systems throughout the manufacturing industry.” ●
