The ASCO Series 047 are manual reset versions of the sturdy ASCO 342 Series (1/4-inch and 3/8-inch NPT) and Series 344 (1/2-inch to 1-inch NPT) valves. The high-flow solenoid valves come in electrically tripped (trips when energized), no-voltage release (trips when de-energized), or free-handle constructions. They are ideal for mission-critical applications in refining and chemical production.
