ASCO 8320G089MO Solenoid Valve

ASCO 8320G089MO is a direct-acting, 3-way, 2-position solenoid valve with normally closed seating and a built-in manual override option. Designed for general-service control of compressed air, water, or light oil, it features a brass body and NBR seals for durable, leak-resistant operation. The valve uses a 1/4-inch nominal pipe size and an orifice of 3/32 inch, yielding a Cv of 0.12 for steady flow control. It is driven by a 120 VAC coil at 60 Hz (110 VAC/50 Hz variants available), drawing about 9.1 W when energized. The coil enclosure is IP66-rated, with a 1/2-inch conduit and 18 inches of leads, enabling installation without an external junction box in many environments; mounting is suitable in either horizontal or vertical orientations. The 8320G089MO is rated for operating pressures from 0 to 110 psi differential and can handle maximum fluid temperatures up to 200°F, making it versatile for air, inert gas, light oil, and water service. The MO suffix indicates a manual override option, allowing manual actuation for testing or maintenance. Typical applications include automatic process control, pneumatic systems, and industrial water or light-oil lines where reliable 120 V control is required.
