ASCO 8040H8-208V Solenoid Valve

The ASCO 8040H8 208V is a heavy-duty 2-way normally closed solenoid valve engineered specifically for low-pressure fuel gas service. Built with a rugged aluminum body and NBR (Buna-N) seals, this valve provides reliable shut-off for pilot or main line control in commercial and industrial combustion systems. Operating on a 208Vac coil, it features a 3/8" NPT connection and a 1.2 Cv flow coefficient, making it suitable for applications with a 0-15 PSI pressure range. The NEMA 4X enclosure ensures superior protection against corrosion and moisture, allowing for dependable performance in demanding mechanical rooms. Designed for fast-acting response times, this ASCO gas valve is a standard component for contractors managing HVAC fuel gas systems and industrial burner manifolds where leak-tight integrity is critical for safety and operational efficiency.

Key Benefits:

• Optimized for Fuel Gas: Specifically designed for air and inert gas applications within the 0-15 PSI range.
• Industrial Durability: The NEMA 4X watertight enclosure protects internal components from harsh environments.
• Reliable Sealing: Equipped with NBR seals to ensure tight shut-off and prevent gas migration in normally closed configurations.
• Standard Fitment: Features a common 3/8" NPT port size for easy integration into existing gas trains.
• High Flow Capacity: Delivers a 1.2 Cv rating to maintain sufficient volume for various burner requirements.

Common Questions:

What is the maximum operating pressure for the ASCO 8040H8?
This valve is rated for a maximum operating pressure differential (MOPD) of 15 PSI for fuel gas applications.

Can this solenoid valve be installed in any orientation?
For optimal performance and to prevent debris accumulation, it is recommended to install the valve with the solenoid vertical and upright.

Is the 208V coil compatible with 240V circuits?
This specific model is wound for 208Vac. Always verify your field voltage with a multimeter to prevent coil burnout or failure to pull in.
