Description
ASCO 8040G22 Two-Way Normally Closed Solenoid Valve
The ASCO 8040G22 is a heavy-duty, two-way normally closed solenoid valve engineered for reliable fuel gas shutoff and control in demanding commercial and industrial HVAC applications. With a rugged aluminum body, NBR (Buna-N) seals, and a NEMA 4X rated enclosure, this valve is built to perform in wet, corrosive, and outdoor environments where protection against dust and moisture is critical.
Key Features
- 2-Way, Normally Closed (NC) configuration — valve closes automatically when de-energized for fail-safe operation
- 1/2″ NPT pipe connection for straightforward installation into standard fuel gas piping systems
- 120VAC coil voltage for compatibility with common commercial control circuits
- 5.4 Cv flow coefficient for efficient fuel gas flow management
- 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 resistance to fuel gases and petroleum-based media
- NEMA 4X enclosure rating — provides protection against corrosion, windblown dust, rain, splashing water, and hosedown
