ASCO 8040H6-240V Solenoid Valve

The ASCO 8040H6-240V is a rugged, 2-way normally closed solenoid valve specifically engineered for low-pressure fuel gas applications. Built with a durable die-cast aluminum body and high-performance NBR (Buna-N) seals, this valve is designed to handle clean fuel gases such as natural gas, propane, and air. With a 1/8" NPT connection and a 1.0 Cv flow coefficient, it provides reliable shut-off control within an operating pressure range of 0 to 15 PSI. The 240Vac coil is housed in a NEMA 4X airtight enclosure, making it suitable for demanding indoor or outdoor installations where protection against corrosion and moisture is critical. This direct-acting fuel gas valve ensures rapid response times and consistent cycling, meeting the technical requirements for industrial burners and commercial furnace pilot lines. Contractors can rely on the ASCO 8040 series for precise flow control and long-term mechanical integrity in gas combustion systems.

• Fuel Gas Compatibility: Optimized for low-pressure gas applications including natural gas and LPG.
• High Flow Performance: Features a 1.0 Cv rating for efficient throughput despite its compact 1/8" port size.
• NEMA 4X Protection: Includes a watertight and corrosion-resistant conduit enclosure for harsh environments.
• Superior Sealing: Integrated NBR seals provide excellent compatibility with hydrocarbons and ensure bubble-tight shut-off.
• No Minimum Pressure: Direct-acting design allows the valve to operate effectively at 0 PSI differential.

What is the maximum operating pressure for the ASCO 8040H6?
This valve is rated for fuel gas service up to 15 PSI. Exceeding this pressure limit can compromise the internal diaphragm and solenoid actuation.

Can this solenoid valve be mounted in any orientation?
For optimal reliability and to prevent debris accumulation in the core tube, it is recommended to mount the valve with the solenoid vertical and upright.

Is the coil on the 8040H6-240V replaceable?
Yes, the 240V coil can be swapped if voltage requirements change, provided the replacement coil is compatible with the 8040 series valve body and enclosure type.
