Emerson has introduced the new ASCO Series 148/149 safety valve and motorized actuator designed for industrial fuel oil burner recirculation and safety shutoff applications. The new solution provides a reliable, versatile tool for industrial users to prevent overpressure, leaks and system malfunctions that can lead to health and safety incidents, with one configuration suited to a wide range of combustion system applications.

The valve and actuator are designed to be used together in one system for fuel oil recirculation as a safety shutoff. The combination is a compact two- and three-way system with a motorized actuator that achieves rapid, reliable fuel line shutoff from an open to closed position in less than one second. It is engineered for robust and reliable operation in harsh outside environments, supporting an operating range from -40ºF to 150ºF (-40ºC to 66ºC). The valve’s high-pressure design makes it a versatile option for use across multiple fuel oil burner applications.
