Description
ASCO JB821453CSA 2-Way Normally Open Fuel Gas Vent Solenoid Valve
The ASCO JB821453CSA is a heavy-duty, 2-way normally open solenoid valve engineered for fuel gas venting applications in commercial and industrial HVAC and combustion systems. Featuring a robust aluminum body, NBR (Buna-N) seals, and a NEMA 1 enclosure with integrated junction box, this valve delivers reliable, code-compliant gas control where it matters most.
Key Features
- 2-Way, Normally Open (N/O) solenoid valve configuration
- 1″ NPT pipe connection for straightforward installation
- 120VAC operating voltage for compatibility with standard commercial power
- 21 Cv flow coefficient for high-capacity gas flow
- 1,179,000 BTU/hr rated capacity for large commercial and industrial burner applications
- 0–5 PSI operating pressure range suitable for low-pressure fuel gas systems
- Aluminum body construction for corrosion resistance and reduced weight
- NBR (Nitrile Butadiene Rubber) seals for reliable, long-lasting fuel gas compatibility
- NEMA 1 enclosure with junction box for indoor installation and easy field wiring
Application
Designed specifically as a fuel gas vent valve, the ASCO JB821453CSA is ideal for use in burner management systems, boiler controls, and combustion equipment where a normally open gas vent is required. When de-energized, the valve remains open to vent gas safely; when energized, it closes to allow system pressurization. This fail-safe behavior is critical for safe burner operation and shutdown sequences.
