Description
The ASCO JB8214240CSA is a heavy-duty, 2-way normally closed solenoid valve engineered for reliable fuel gas shutoff in commercial and industrial HVAC and combustion applications. With a generous 3-inch port size available in NPT or flange connection, this valve delivers exceptional flow capacity and is built to perform in demanding environments.
Key Features
- 2-way, normally closed (N/C) operation ensures the valve defaults to the safe, closed position upon loss of power
- 3″ pipe connection compatible with NPT or flange configurations for installation flexibility
- 120VAC coil voltage for standard commercial power compatibility
- High flow capacity of 105 Cv — rated for up to 5,661,700 BTU/hr fuel gas throughput
- Operating pressure range: 0–5 PSI, ideal for low-pressure fuel gas systems
- Aluminum body construction for a lightweight yet durable build
- NBR (Buna-N) seals provide excellent resistance to natural gas, propane, and other common fuel gases
- NEMA 1 enclosure with integrated junction box for clean, protected wiring connections
