ASCO
ASCO
Official website: www.asco.com ↗ASCO, founded in 1888 and now part of Emerson, is the world’s reference name in solenoid valves. Its 2/2, 3/2 and 4/2 solenoid ranges — direct-operated, pilot-operated and in every material from brass to special alloys — are the default specification for automated isolation and pilot duty.
In the control-valve world, ASCO solenoids are the trip and isolation devices between positioner and actuator, and the brand’s breadth in media, pressure and hazardous-area certifications makes it the catalogue engineers reach for first.
