Description
The ASCO L8040G22 is a 2-way, normally closed solenoid valve engineered specifically for fuel gas applications in commercial and industrial HVAC systems. Built with a durable aluminum body and NBR (Buna-N) seals, this valve delivers reliable shutoff performance in demanding environments where moisture and corrosion resistance are critical.
Key Features
- 2-way, normally closed (N/C) configuration — valve closes when de-energized for fail-safe operation
- 1/2″ NPT pipe connection for straightforward installation into standard fuel gas lines
- 120VAC coil voltage for compatibility with common commercial control circuits
- 5.4 Cv flow coefficient for efficient fuel gas flow management
- Rated operating pressure range: 0–2 PSI, ideal for low-pressure fuel gas service
- Aluminum body construction — lightweight yet robust for long service life
- NBR (Nitrile Butadiene Rubber) seals — compatible with natural gas and other fuel gas media
- NEMA 4X enclosure rating — provides protection against dust, water, and corrosion for indoor and outdoor installations
- 72″ (6 ft) lead wires for flexible wiring and installation convenience

Application
The ASCO L8040G22 is well-suited for use in commercial heating systems, gas-fired equipment, burner management systems, and other fuel gas control applications where a reliable, normally closed shutoff is required. The NEMA 4X-rated enclosure makes it an excellent choice for installations exposed to moisture or washdown environments. Its aluminum body keeps weight low while maintaining structural integrity, and the long 72″ leads simplify panel wiring in tight mechanical spaces.
