The Asco EF8015B201 Solenoid Valve is a pilot-operated, manual reset valve with an explosion-proof enclosure and electrically tripped construction. It closes when the coil is energized and requires manual reset after trip. Ideal for hazardous locations where reliable, deliberate shutoff is critical in compressed air, inert gas, water, or light oil systems.
