ASCO 8214G33 Fuel Gas Solenoid Vent Valve Overview
The ASCO 8214G33 is a 2-way, normally open solenoid valve engineered specifically for fuel gas vent applications in commercial and industrial HVAC and combustion systems. Featuring a robust aluminum body, NBR seals, and a NEMA 4X enclosure, this valve delivers reliable, code-compliant performance in demanding environments where moisture and corrosion resistance are critical.
Key Features
- 2-way normally open (N/O) configuration — opens when de-energized for safe fuel gas venting
- 3/4″ NPT pipe connection for straightforward installation into standard gas lines
- 120VAC coil voltage for compatibility with common commercial control circuits
- 5.1 Cv flow coefficient supporting up to 247,500 BTU/hr capacity
- Operating pressure range: 0–5 PSI, ideal for low-pressure fuel gas systems
- Aluminum body construction for lightweight durability and corrosion resistance
- NBR (Buna-N) seals providing excellent compatibility with natural gas and other fuel gases
- NEMA 4X enclosure rating — suitable for indoor and outdoor use, protected against dust, water, and corrosion

Application
The ASCO 8214G33 is designed for use as a fuel gas vent valve in burner management systems, boilers, and commercial combustion equipment. The normally open design ensures the vent path remains open during a de-energized (safe) state, making it an essential safety component in gas train assemblies. Its NEMA 4X rating makes it well-suited for installations exposed to washdowns, outdoor weather, or high-humidity environments.
