ASCO 8040G22 Solenoid Valve

The ASCO 8040G22 is a robust 2-way normally closed solenoid valve designed specifically for fuel gas service. Built with a high-grade aluminum body and NBR seals, this valve is engineered to handle low-pressure combustible gas pipelines with a 5.4 Cv flow coefficient. Operating on 120V/60Hz, it features a 1/2" NPT connection and is rated for a direct-acting pressure range of 0-2 PSI. The NEMA 4X enclosure provides superior protection against corrosion and environmental ingress, making it suitable for demanding industrial and commercial combustion systems. By utilizing a normally closed configuration, the valve ensures the flow of fuel gas is immediately restricted upon loss of power, meeting critical safety requirements for burner management and gas train assemblies. This ASCO RedHat series component is the industry standard for reliable gas shutoff valve applications where high-flow capacity and tight shut-off are non-negotiable.

Key Benefits:

• High Flow Efficiency: The 5.4 Cv rating ensures minimal pressure drop across the 1/2" NPT ports.
• Rugged Construction: The aluminum body and NEMA 4X rating provide durability in wash-down or corrosive environments.
• Zero Minimum Differential: The direct-acting design allows the valve to function reliably even at 0 PSI.
• Industry Compliance: Specifically designed for fuel gas safety shutoff in furnace and boiler applications.
• Reliable Sealing: Equipped with Buna-N (NBR) elastomers for consistent performance with gaseous fuels.

Common Questions:

Can the ASCO 8040G22 be used with liquid fuels?
No, this model is specifically rated for fuel gas. For liquid or oil-based applications, a different seal and body material compatibility check is required.

What is the maximum operating pressure for this solenoid?
The 8040G22 is rated for a maximum operating pressure differential of 2 PSI for gas service.

How do I mount this valve in a gas train?
The valve is typically mounted in a vertical and upright position to ensure optimal plunger movement and longevity of the NBR seals.
