The Asco 8025B214 Solenoid Valve is a manually reset, pilot-operated unit designed for general service flow control in air, inert gas, water, and light oil systems. This Latched Closed, No Voltage Release configuration keeps the valve closed while the coil is energized and trips it open when power is lost.
