The Asco 8015B203 Solenoid Valve is a pilot-operated, manual reset valve designed for critical applications that demand deliberate restart procedures. Its electrically tripped construction closes the valve when energized and requires manual reset to resume flow. Ideal for light oil, water, and air handling systems in general industrial environments.
