The ASCO Red-Hat 8215G030 is a 2-way, normally closed solenoid valve designed primarily for air and fuel gas control in commercial and industrial systems.
👉 “Red-Hat” refers to ASCO’s well-known solenoid coil/enclosure design, commonly used in HVAC, burners, and process systems.
Valve type: 2-way, normally closed (fails closed)
Pipe size: 3/4" NPT
Body material: Aluminum
Flow coefficient: ~Cv 5.1
Pressure range: 0–50 PSI
Temperature range: ~32°F to 125°F
Media: Air, inert gas, fuel gas
👉 Available in multiple coil voltages:
120 VAC
24 VAC / 24 VDC
(depending on model suffix)
De-energized: valve is closed (no flow)
Energized: coil opens the valve → allows flow
👉 This makes it a fail-safe shutoff valve, especially important for gas systems.
🔥 Gas burners / combustion systems
🌬️ HVAC air control
🏭 Industrial automation (low-pressure gas/air)
🚧 Safety shutoff / block-and-bleed setups
Example: Often used as a gas safety shutoff valve in boilers or rooftop units.
Designed for low-pressure, high-flow gas/air systems
Pilot-operated design = better flow vs direct-acting valves
Not typically used for water or high-pressure liquid systems
