ASCO WT8401B105M Dual Air Solenoid Valve 6.3W 20-150 PSI 110 120 VAC

ASCO WT8401B105M is a four‑way, two‑position dual‑solenoid valve in the ASCO 8401 family, intended for directing air or inert gas in compact pneumatic circuits. With dual coils, it holds its last position when power is removed, a bistable configuration that supports energy‑efficient, fail‑safe operation in line‑driven systems. The coil is rated at 6.3 watts and accepts 110–120 VAC input across typical 50/60 Hz service; the valve is specified for an operating pressure range of 20 to 150 psi for air‑inert gas services. Porting comprises four 1/4‑inch (FPT) connections, and the WT8401B105M variant uses an aluminum body with direct‑mount compatibility (sub‑base mounting optional) to simplify installation. Common applications include actuating pneumatic cylinders, burner air control, HVAC equipment, and other automation tasks that require reliable 4‑way/2‑position switching of compressed air or inert gas in industrial equipment.
