ASCO 8040H007 Gas Combustion Solenoid Valve – 24V/60Hz – Normally Closed – 1/4" NPT

Product Spec Sheet (PDF)

The ASCO 8040H007 24V/60Hz Gas Combustion Solenoid Valve is a normally closed safety shut-off valve designed to control the flow of natural gas, LP gas, air, and inert gases in combustion systems. This electrically operated valve opens when energized and automatically closes when power is removed, providing fast and reliable protection for gas-fired equipment.

Commonly used in burner management systems and gas trains, the ASCO 8040H007 helps ensure safe operation of boilers, furnaces, ovens, and other heating equipment. Its compact design, durable aluminum body, and dependable solenoid operation make it ideal for both OEM installations and replacement in commercial and industrial combustion systems.

Operating on 24 volts AC at 60 Hz, this valve is compatible with many low-voltage control circuits used in HVAC equipment and automated burner systems. The 1/4" NPT threaded connection allows easy installation in pilot lines, burner manifolds, and gas supply piping.

Designed for reliability in demanding environments, the ASCO 8040 series valves are widely used across HVAC, manufacturing, food service, and industrial heating applications where dependable gas shut-off control is critical.
