Description
ASCO JB8214290CSA Fuel Gas Shutoff Solenoid Valve Overview
The ASCO JB8214290CSA is a heavy-duty, 2-way normally closed solenoid valve engineered for reliable fuel gas shutoff applications in commercial and industrial HVAC and combustion systems. With a generous 2-1/2″ connection size available in NPT or flange configurations, this valve delivers exceptional flow capacity and flexibility for a wide range of installations.
Key Features
- 2-way, normally closed (N/C) solenoid valve — closes automatically on power loss for fail-safe fuel shutoff
- 2-1/2″ connection size with NPT or flange end options for versatile installation
- 120VAC operating voltage for standard commercial power compatibility
- High flow capacity: 104 Cv flow coefficient supporting up to 5,607,800 BTU/hr
- Operating pressure range: 0–5 PSI, ideal for low-pressure fuel gas systems
- Aluminum valve body for lightweight durability and corrosion resistance
- NBR (Nitrile Butadiene Rubber) seals for reliable compatibility with natural gas and other fuel gases
- NEMA 1 enclosure with junction box for safe, organized wiring connections in indoor environments

Application & Benefits
Designed for fuel gas shutoff duty, the ASCO JB8214290CSA is well-suited for use in commercial boilers, burner management systems, rooftop units, and industrial heating equipment. The normally closed design ensures the valve defaults to the safe, closed position whenever power is interrupted, providing critical protection against uncontrolled gas flow. The aluminum body keeps the valve lightweight without sacrificing durability, while NBR seals ensure long-term compatibility with natural gas and similar fuel gases. The NEMA 1 junction box enclosure simplifies field wiring and keeps connections protected in indoor mechanical room environments.
