ASCO 8320G198 Solenoid Valve

ASCO 8320G198 is a direct-acting, three‑way general‑service solenoid valve with 1/4" NPT ports and a brass body. It is a normally closed (N/C) device that routes flow between two ports while exhausting the third when energized, making it suitable for air, water, or oil service in instrumentation and process control systems. The 8320 family is offered with AC coils for 120 VAC/60 Hz or 110 VAC/50 Hz operation, and coil power varies by the installed coil class (typical 50 Hz values around 8.1 W for a 6.1/F coil and 11.1 W for a 9.1/F coil). Standard construction uses Buna-N seals compatible with the brass body, and the valve is designed for low‑pressure service with an operating pressure range up to 40 psi. Liquid temperatures can be as high as 200°F (93°C) and ambient temperatures up to 150°F (66°C). In certain configurations, ASCO valves in this series can be specified for use with dry natural gas service using the EF prefix. The 8320G198 designation identifies a 1/4" NPT, 3‑way, normally closed variant within this robust general‑service family, delivering compact, reliable actuation for automation lines and fluid control tasks where quick isolation and venting are required.
