ASCO 8040H7 Solenoid Valve

The ASCO 8040H7 is a specialized 2-way normally closed solenoid valve engineered specifically for low-pressure fuel gas service. Designed for reliability in commercial and industrial combustion systems, this valve features a 1/4" NPT connection and an aluminum body that balances durability with weight efficiency. Operating on 120Vac, the 8040H7 provides a 1.1 Cv flow coefficient, optimized for the 0-15 PSI pressure range. It utilizes NBR (Nitrile) seals to ensure tight shut-off and chemical compatibility with standard fuel gases. The assembly is housed in a NEMA 4X enclosure, providing superior protection against corrosion and environmental ingress, making it suitable for demanding mechanical rooms. This direct-acting valve is a critical component for gas pilot control and main line shut-off applications where consistent opening and closing cycles are required. Contractors value this series for its straightforward integration into existing HVAC fuel trains and its ability to maintain seat integrity under fluctuating line pressures.

• Fuel Gas Optimization: Specifically rated for 0-15 PSI, making it ideal for low-pressure gas burner manifolds and pilot lines.
• Hardened Construction: Lightweight aluminum body reduces strain on copper or black iron piping while maintaining structural integrity.
• Environmental Protection: The NEMA 4X rated coil enclosure allows for installation in washdown or corrosive environments without risking coil failure.
• Reliable Sealing: NBR elastomers provide a positive seal-off to prevent gas leakage in the closed position.
• High Flow Capacity: A 1.1 Cv rating ensures minimal pressure drop across the valve, maintaining burner efficiency.

Common Questions

What is the maximum operating pressure differential for the ASCO 8040H7?
This valve is designed for low-pressure systems and should not exceed a 15 PSI differential to ensure safety and proper seat operation.

Can this solenoid valve be used for liquid propane?
Yes, the 8040H7 is compatible with fuel gases including natural gas, propane (LP), and air, provided the pressure remains within the 0-15 PSI range.

Does this valve require a minimum pressure to open?
No, as a direct-acting valve, it does not require a minimum operating pressure to actuate, though it is limited to a maximum of 15 PSI.
