ASCO 8320B177 Solenoid Valve

ASCO 8320B177 is a compact three-way solenoid valve in a brass body with 1/4-inch NPT ports, designed for general-service fluid control in small-diameter lines. It belongs to ASCO's 8320 Series (Series 320) of direct-acting valves, featuring three ports all in the valve body for inlet, outlet, and exhaust. The coil is available for 120 VAC at 60 Hz or 110 VAC at 50 Hz, matching common North American and international power standards; the specific 8320B177 variant appears as a dual-frequency coil option. The valve is rated for up to 250 psi maximum working pressure, suitable for water, compressed air, and many inert gases in automation and process lines. Seals are typically NBR, and the valve uses standard 1/4" NPT connections for easy retrofit in existing piping.
