Description
The ASCO JKF8040H8 is a heavy-duty, 2-way normally closed solenoid valve engineered specifically for fuel gas applications in commercial and industrial HVAC and combustion systems. Featuring a robust aluminum body with NBR (Buna-N) seals, this valve delivers reliable, leak-tight shutoff performance across a wide range of demanding environments.
Key Features
- 2-way, normally closed (NC) operation — valve closes automatically upon de-energization for fail-safe fuel shutoff
- 3/8″ NPT pipe connection for straightforward installation into standard fuel gas lines
- 1.2 Cv flow coefficient for efficient gas flow management
- Operating pressure range: 0–15 PSI, suitable for low-pressure fuel gas service
- 120VAC coil voltage for compatibility with standard commercial power supplies
- High-temperature coil rated for elevated ambient and process temperatures
- Aluminum body construction — lightweight yet durable for long service life
- NBR (Nitrile Butadiene Rubber) seals provide excellent resistance to fuel gases and hydrocarbons
Enclosure & Electrical Details
- NEMA 4X rated enclosure — provides protection against corrosion, dust, and water ingress (indoor/outdoor use)
- Integrated junction box for clean, protected wiring connections
- Screw terminals for fast, secure field wiring without special tools
Typical Applications
- Fuel gas shutoff on commercial boilers and furnaces
- Burner management and combustion control systems
- Industrial gas distribution and process control
- OEM equipment requiring a reliable, code-compliant gas solenoid valve
