The Asco EF8015B209 Solenoid Valve is a manual reset, steam-rated solution for medium to large thermal systems. Its latched-open, electrically tripped operation ensures secure shutoff and manual restart only after conditions are verified. Built to withstand saturated steam, it’s ideal for applications that require controlled flow interruption and restart protection.
