The Asco 8015B209 Solenoid Valve is a manual reset steam valve designed for mid-to-large capacity thermal systems requiring deliberate restart protection. With a brass body, PTFE disc, and EPDM/FPM/PTFE seals, it can withstand saturated steam environments. The valve trips closed when energized and requires manual reset after power interruption.
