The Asco EF8015B207 Solenoid Valve is a latched-open, electrically tripped, manual reset valve engineered specifically for steam service. It supports the controlled isolation of high-temperature flow with materials selected for heat resistance and steam compatibility. Perfect for process lines, sterilizers, and heating circuits that require an operator-verified restart after a trip event.
