Description
ASCO 821463CSA Solenoid Fuel Gas Vent Valve Overview
The ASCO 821463CSA is a 2-way, normally open solenoid valve engineered specifically for fuel gas venting applications in commercial and industrial HVAC and combustion systems. With a robust aluminum body, NBR (Buna-N) seals, and a NEMA 1 enclosure, this valve delivers dependable, code-compliant shutoff performance in demanding environments.
Key Features
- 2-way, normally open (N.O.) solenoid valve configuration — opens when de-energized, closes when energized
- 1-1/4″ NPT pipe connection for straightforward installation into standard fuel gas piping
- 120VAC coil voltage for compatibility with common commercial control circuits
- High flow capacity with a 32 Cv flow coefficient, supporting up to 1,538,750 BTU/hr
- Operating pressure range: 0–5 PSI — ideal for low-pressure fuel gas vent service
- Aluminum body construction — lightweight, corrosion-resistant, and durable
- NBR (Nitrile Butadiene Rubber) seals — excellent compatibility with natural gas and other fuel gases
- NEMA 1 enclosure rating — suitable for general-purpose indoor installations
Application
The ASCO 821463CSA is designed for use as a fuel gas vent valve in burner management and combustion safety systems. In a normally open configuration, the valve vents gas safely when the system is de-energized, making it a critical safety component in boiler, furnace, and burner train assemblies. It is well-suited for installations requiring reliable, automatic gas venting to atmosphere between safety shutoff valves.
