ASCO 8040H007 Gas Combustion Solenoid Valve – 120V/60Hz, 110V/50Hz – Normally Closed – 1/4" NPT

Product Spec Sheet (PDF)

The ASCO 8040H007 Gas Combustion Solenoid Valve is a reliable safety shut-off valve designed for fuel gas control in combustion systems. This normally closed, electrically operated valve automatically stops gas flow when power is removed, helping protect burners, appliances, and industrial heating equipment.

Engineered for dependable performance, the 8040H007 is commonly used in boilers, furnaces, ovens, and other gas-fired equipment where precise and safe gas flow control is essential. When energized, the valve opens to allow gas flow to the burner system. When de-energized, the valve closes immediately to shut off the gas supply, ensuring safe system operation.

The valve operates on 120V AC at 60 Hz or 110V AC at 50 Hz, making it compatible with a wide range of commercial and industrial combustion systems. Its compact 1/4" NPT connection and durable aluminum body allow for easy installation in both new equipment and replacement applications.

Built to meet demanding combustion safety requirements, the ASCO 8040 Series valves are widely used across HVAC, industrial heating, food processing, and commercial cooking industries.
