Description
ASCO 821483CSA Fuel Gas Solenoid Vent Valve Overview
The ASCO 821483CSA is a heavy-duty, 2-way normally open solenoid vent valve engineered for demanding fuel gas applications. Featuring a 2″ NPT connection, this valve delivers an impressive flow coefficient of 60 Cv and a rated capacity of 2,924,500 BTU/hr, making it an ideal choice for commercial and industrial burner management systems, boiler fuel trains, and gas-fired equipment. The normally open configuration ensures the valve remains open during a de-energized state, providing a reliable fail-safe vent path as required by fuel gas safety codes.
Key Features
- 2-way, normally open (N.O.) solenoid valve configuration for fail-safe fuel gas venting
- 2″ NPT pipe connection for straightforward installation into standard fuel gas piping
- 120VAC, 60 Hz coil voltage for compatibility with standard commercial power supplies
- High flow coefficient of 60 Cv supports high-capacity burner and boiler applications
- Rated capacity of 2,924,500 BTU/hr for large commercial and industrial fuel gas systems
- Operating pressure range: 0–5 PSI, suitable for low-pressure fuel gas service
- Aluminum body construction — lightweight yet durable for long service life
- NBR (Buna-N) seals provide excellent resistance to natural gas, propane, and other fuel gases
- NEMA 1 enclosure rating for general-purpose indoor installations

Application
The ASCO 821483CSA is designed for use as a vent valve in fuel gas safety shutoff systems, burner management trains, and industrial combustion equipment. Its normally open design allows gas to vent freely when the system is de-energized, preventing dangerous pressure buildup between safety shutoff valves. This valve is well-suited for boilers, industrial furnaces, process heaters, and other large-capacity gas-fired equipment requiring reliable, code-compliant vent valve performance.
