Description
The ASCO SV311A01N6BF5 is a 1/4 inch normally closed, direct-acting solenoid gas shut-off valve designed for commercial and industrial combustion systems. It operates on 24 V AC and provides reliable on/off control of gas for pilot or main lines in burners, furnaces, boilers, and HVAC equipment. The valve has a threaded NPT connection, a differential pressure rating up to 15 psi, and a flow coefficient (Cv) of approximately 1.1, with a nominal capacity around 59,000 BTU/hr. It features a direct lift design with soft seating for tight shut-off and includes a 1/8 inch NPT downstream test port for routine maintenance. The aluminum body with NBR seals and stainless steel internal components ensures durability and long service life. Opening and closing occur in under 1 second.
