ASCO 8040H6 Solenoid Valve

The ASCO 8040H6 is a professional-grade 2-way normally closed solenoid valve engineered for fuel gas service in residential and commercial combustion systems. Featuring a lightweight aluminum body and NBR seals, this valve provides reliable low-pressure shutoff for natural gas and propane applications. With a 1/8" NPT connection and a 1.0 Cv flow coefficient, it handles pressures from 0 to 15 PSI efficiently. The 120V/60Hz coil is protected by a NEMA 4X enclosure, making it suitable for demanding environments requiring water-tight and corrosion-resistant performance. This ASCO RedHat valve is a standard choice for gas pilot line control and small burner setups, ensuring tight seating and rapid response times during cycle changes. For contractors maintaining HVAC fuel trains, the 8040H6 offers a robust drop-in solution that meets the rigorous demands of combustion gas shutoff protocols.

Key Benefits for Contractors

• Fuel Gas Compatibility: Specifically designed for natural gas, propane, and air, ensuring safe gas burner valve operation.
• Zero Minimum Pressure: Operates reliably at 0 PSI inlet pressure, ideal for gravity-fed or low-pressure gas lines.
• Environmental Protection: The NEMA 4X enclosure provides superior protection against moisture and corrosive elements.
• Optimized Flow: High-flow 1.0 Cv rating within a compact 1/8" footprint minimizes pressure drop across the valve.
• Durable Sealing: Nitrile (NBR) elastomers provide a positive seal and resist degradation from fuel gas particulates.

Common Questions

What is the maximum operating pressure for the ASCO 8040H6?
This valve is rated for a maximum operating pressure differential (MOPD) of 15 PSI for fuel gas applications.

Can this valve be mounted in any orientation?
While ASCO valves are versatile, it is recommended to mount the 8040H6 solenoid with the coil upright and vertical to prevent sediment buildup in the core tube and ensure maximum longevity.

Is the 8040H6 suitable for outdoor installation?
Yes, the NEMA 4X rating indicates the housing is designed for protection against hose-directed water and corrosion, making it suitable for outdoor fuel train assemblies.
