Description
The ASCO 8214280CCSA is a heavy-duty, 2-way normally closed solenoid valve engineered specifically for fuel gas shutoff applications in commercial and industrial HVAC and combustion systems. With a generous 2-inch connection size available in NPT or flange configurations, this valve delivers exceptional flow capacity and reliable shutoff performance where it matters most.
Key Features
- 2-way, normally closed (NC) solenoid valve — de-energizes to the closed/safe position
- 2″ NPT or flange connection for flexible installation options
- 120VAC coil voltage for standard commercial power compatibility
- High flow coefficient of 55 Cv for minimal pressure drop across the valve
- Rated capacity of 2,940,500 BTU/hr — ideal for large commercial and industrial burner systems
- Operating pressure range: 0–5 PSI, suited for low-pressure fuel gas service
- Aluminum body construction for lightweight durability and corrosion resistance
- NBR (Buna-N) seals for reliable compatibility with natural gas and other fuel gases
- NEMA 1 enclosure for indoor general-purpose environments
- Proof of Closure (POC) switch included — provides a verified closed-position signal for safety interlocks and burner management systems

Application
The ASCO 8214280CCSA is designed for use as a safety shutoff valve in fuel gas supply lines serving commercial boilers, industrial burners, furnaces, and other combustion equipment. The integrated Proof of Closure switch enables direct integration with burner management systems (BMS) and flame safeguard controls, confirming valve position before allowing ignition sequences to proceed. The normally closed design ensures the gas supply is automatically interrupted upon loss of power, providing a fail-safe layer of protection for life safety and equipment protection.
