Description
ASCO JB821463CSA Fuel Gas Solenoid Vent Valve Overview
The ASCO JB821463CSA is a heavy-duty 2-way normally open solenoid valve engineered for fuel gas venting applications in commercial and industrial HVAC and combustion systems. With a robust aluminum body, NBR seals, and a NEMA 1 enclosure with junction box, this valve delivers reliable, code-compliant performance in demanding environments.
Key Features
- 2-Way Normally Open (N.O.) configuration — opens when de-energized for safe fuel gas venting
- 1-1/4″ NPT connection for straightforward installation into standard piping systems
- 120VAC coil voltage for compatibility with common commercial control circuits
- High flow capacity with a 32 Cv flow coefficient — rated at 1,538,750 BTU/hr
- Operating pressure range: 0–5 PSI, ideal for low-pressure fuel gas vent service
- Aluminum body construction for lightweight durability and corrosion resistance
- NBR (Nitrile Butadiene Rubber) seals for reliable compatibility with fuel gas media
- NEMA 1 enclosure with integrated junction box for clean, protected wiring terminations

Application
The JB821463CSA is designed for use as a fuel gas vent valve in burner management systems, boilers, furnaces, and other combustion equipment where a normally open vent valve is required between two safety shutoff valves. When energized, the valve closes to allow gas flow to the burner; when de-energized, it opens to safely vent any gas trapped between the safety valves to atmosphere, ensuring compliance with safety standards for gas-fired equipment.
