ASCO L8040G23 2-Way Normally Closed Solenoid Valve Overview
The ASCO L8040G23 is a heavy-duty, 2-way normally closed solenoid valve engineered specifically for fuel gas applications. Featuring an aluminum body with NBR (Buna-N) seals, this valve delivers reliable shutoff performance in demanding commercial and industrial HVAC and combustion systems. The NEMA 4X enclosure provides protection against corrosion, dust, and water ingress, making it suitable for both indoor and outdoor installations. With a generous 72-inch lead wire, installation flexibility is built right in.
Key Features
- 2-Way, Normally Closed (NC) operation — valve closes automatically when de-energized for fail-safe fuel shutoff
- 3/4″ NPT pipe connection for straightforward integration into standard fuel gas piping
- 120VAC coil voltage for compatibility with common control circuits
- 9.5 Cv flow coefficient for efficient gas flow with minimal pressure drop
- Operating pressure range: 0–2 PSI, optimized for low-pressure fuel gas service
- Aluminum body construction — lightweight yet durable for long service life
- NBR (Nitrile Butadiene Rubber) seals — excellent compatibility with natural gas and other fuel gases
- NEMA 4X enclosure rating — resistant to corrosion, rain, splashing water, and hose-directed water
- 72-inch (6 ft.) lead wires for flexible wiring runs and easier panel connections
