Schneider Electric 9013 ASG-8 Pressure Switch

Schneider Electric Square D 9013-ASG-8 Pumptrol pressure switch closes at 80 psi and opens at 100 psi, delivering a precise, built-in control point for cycling pumps in residential or light commercial water systems, booster sets, and irrigation controllers. As a member of the 9013 Class G family, this diaphragm-style switch uses a 3/8-inch male pipe thread pressure connection for standard installations and is designed to withstand the recurring mechanical cycling typical of pump control equipment. The 9013-ASG-8 is a configured variant within the Pumptrol 9013 series with a fixed 20 psi differential (80/100 psi), offering reliable on/off operation without external relay hardware and for long service life. Used to automate pump operation in wells, boilers, and small compressors, it embodies Schneider Electric's Pumptrol lineage and adheres to the Class G porting standard for 3/8" pressure connections. The 3/8 in. porting and 80/100 psi thresholds align with common well-pump and boiler-control configurations.
