The Asco EF8025B205 Solenoid Valve is engineered for large-volume applications in hazardous environments. The No Voltage Release function allows the valve to remain open while energized and closes automatically when power is interrupted. Its durable brass body and an NBR diaphragm make it suitable for controlling high flow rates of air, inert gas, water, and light oil.
