ASCO 237-569B Two-Position 3/2 Way Solenoid Valve

ASCO 237-569B is a solenoid coil assembly designed to actuate ASCO NUMATICS two-position 3/2-way valves. Sold as a standalone coil rather than a complete valve, the 237-569B provides the electrical actuation required to shift the valve spool between its two ports, enabling precise control of compressed air or inert gas in small automation circuits. This coil belongs to ASCO's general-service line and is commonly used as a replacement part for ASCO 3/2 valves in industrial pneumatic systems, packaging equipment, manufacturing lines, and laboratory instrumentation. Because the 237-569B designation identifies the coil compatible with specific ASCO valve bodies, users should verify compatibility with their valve model before replacement. The part is typically stocked by distributors as a ready-to-install actuator for a compact, space-saving valve arrangement, offering quick energization and reset of the valve without an external pilot source. In service, it enables standard two-position control where an on/off electrical signal toggles airflow through the valve, supporting straightforward control logic for sequencing, timing, and interlocks in automated systems.
