The Asco EF8015B226 Solenoid Valve is a stainless steel, explosionproof valve built for corrosive and high-temperature environments. It stays locked in the closed position after tripping, requiring both electrical input and manual reset to resume operation. This is ideal for facilities that require strict control over the flow restart process.
