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 series provides a versatile tool for users to prevent overpressure, leaks and system malfunctions. 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 fuel line shutoff from an open to closed position in less than one second. The system features a high-flow and high-pressure design that enhances heat output and meets approvals from UL, FM and CSA certifications, improving fuel oil combustion system performance through higher pressure and media temperature tolerance. It supports an operating range from -40 to 150℉.
