ASCO WPIS8408B006 Trip Valve

ASCO WPIS8408B006 Trip Valve is a direct-acting, normally closed, 3-way solenoid valve designed for air and inert gas service. In the de-energized state it remains closed, providing a fail-safe condition in pneumatic circuits. The valve uses 1/4-inch ports for compact installation in instrumentation panels and control lines. It is part of ASCO’s 8408-series family and accepts AC control voltages; coil options documented for this model include 120/60 VAC and 110/50 VAC, enabling compatibility with common electrical supplies. The WPIS8408B006 designation is listed in ASCO's Catalog 34 and appears in distributor inventories; some listings note NOS (new old stock). With a three-port configuration, the valve can be integrated to control air or inert gas flow in automated systems, making it suitable for various pneumatic applications within industrial environments. Interchangeability within the ASCO WPIS/8408 family supports repair or refurbishment projects for legacy equipment.
