The Asco EF8015B213 Solenoid Valve is designed for high-reliability shutoff in heated, chemically aggressive fluid systems located in classified environments. Its stainless steel construction and PTFE disc offer durable corrosion resistance, while the explosionproof enclosure makes it suitable for hazardous process areas. Its latched-open, electrically tripped configuration ensures restart only occurs after manual verification.
