ASCO 8040G22-24V Solenoid Valve

The ASCO 8040G22-24V Solenoid Valve is a 2-way normally closed gas shutoff valve engineered for critical combustion control in commercial and industrial burners. This 1/2" NPT fuel gas valve features a robust aluminum body and high-grade NBR seals, ensuring reliable performance within a pressure range of 0-2 PSI. Optimized for 24Vac control circuits, this unit delivers a flow factor of 5.4 Cv and a gas capacity of approximately 291,000 BTU/hr, making it a standard choice for gas pilot or main control applications. The direct-acting design allows for operation in any mounting position, while the NEMA 4X enclosure provides superior protection against water ingress and corrosion. Integrated 1/8" NPT upstream and downstream pipe taps simplify pressure testing and routine maintenance. As a UL listed and CSA certified safety shutoff valve, the 8040G22-24V is built to meet rigorous mechanical standards for HVAC combustion systems and industrial fuel lines.

Common Questions

What is the BTU capacity for the ASCO 8040G22?
This valve is rated for approximately 291,000 BTU/hr at common operating pressures, suitable for most commercial pilots and smaller industrial burners.

Can I use this valve for high-pressure gas lines?
No, this specific model is rated for a maximum operating pressure differential (MOPD) of 2 PSI. Exceeding this limit can cause internal damage or failure to open.

Is the 8040G22-24V suitable for outdoor installation?
Yes, the NEMA 4X enclosure is watertight and corrosion-resistant, making it appropriate for outdoor equipment racks and exposed burner assemblies.
