ASCO Numatics 031SA4152000030 Solenoid Valve

The ASCO Numatics 031SA4152000030 is a MK3 Series four-way, two-position solenoid valve with a single direct-solenoid, spring-return actuator, designed for pneumatic control in compact manifolds. It features side- and bottom-porting in a 1/8" NPT configuration and a DIN plug-in AC solenoid coil rated for 110–120 VAC at 50–60 Hz, enabling straightforward wiring in industrial control panels. This 4/2 valve provides two actuation positions controlled by energizing the coil or releasing it, allowing switching between air supply and exhaust paths in a compact footprint suitable for automation equipment and multi-valve manifolds. Its MK3 construction supports reliable integration into pneumatic circuits where space is at a premium, and its 1/8" NPT ports and DIN wiring simplify installation and replacement in standard industrial environments.
