Description
The ASCO SV311A01N6CF5 is a 3/8‑inch normally closed (N/C), direct‑acting solenoid gas shut‑off valve designed for pilot and main gas control in commercial and industrial combustion systems. It operates on 24 V AC, makes or blocks gas flow in response to electrical power, and is suitable for low‑pressure fuel service up to about 15 psi. The valve uses a direct lift design with soft seating to provide tight shut‑off, and includes a downstream 1/8 inch NPT test port with plug for routine maintenance and pressure testing. The body is aluminum with durable internal parts, and the valve is suitable for ambient temps up to ~175 °F. These features make it appropriate for burner pilot circuits, furnace fuel interdiction, packaged heater controls, and similar applications.
