Description
The ASCO 8214G281 is a heavy-duty, 2-way normally closed solenoid shutoff valve engineered for reliable fuel gas control in commercial and industrial HVAC applications. With a generous 2-inch port size available in NPT or flange end connections, this valve delivers high-flow performance with a 55 Cv flow coefficient capable of handling up to 2,940,500 BTU/hr — making it well-suited for large burner systems, boilers, and process heating equipment.
Designed to operate on 120VAC power, the valve snaps shut upon de-energization, providing a critical safety shutoff function in the event of a power loss or control signal interruption. The 0–5 PSI operating pressure range is ideal for low-pressure fuel gas distribution systems.
Key Features
- 2-way, normally closed (NC) operation — closes automatically on power loss for fail-safe fuel shutoff
- 2″ port size with NPT or flange end connections for flexible installation
- 120VAC coil voltage for compatibility with standard commercial control circuits
- 55 Cv flow coefficient supporting up to 2,940,500 BTU/hr capacity
- Operating pressure range: 0–5 PSI, optimized for low-pressure fuel gas service
- Aluminum body construction — lightweight yet durable for demanding environments
- NBR (Buna-N) seals for reliable compatibility with natural gas and other common fuel gases
- NEMA 4X enclosure rating — provides protection against corrosion, dust, and water ingress for indoor and outdoor installations
