The Asco EF8015B205 Solenoid Valve is a pilot-operated, manual reset model designed for reliably isolating large process lines. Its tripped-close design supports controlled shutdowns in high-flow fluid systems, while the manual reset function ensures that a restart only occurs when conditions are verified. Ideal for utility, fuel, and industrial circuits requiring deliberate flow interruption.
