Asco Explosion Proof Gas Solenoid Valve NPT Normally Closed

The Asco Series 8215 explosion proof gas solenoid valve is a 2-way, normally closed solenoid valve with NPT threaded connections. It is made for air-fuel gas shutoff and blocking in low-pressure systems. Also called a gas shutoff valve, safety shutoff valve or solenoid blocking valve, it stays closed when de-energized and opens when the coil is energized. That makes it a dependable fail-safe for burners, boilers and other combustion equipment.

Key Features:

• Explosion proof enclosure: The solenoid enclosure is built for hazardous locations where flammable gases or vapors may be present.
• Normally closed, 2-way design: Gas flow shuts off automatically when power is removed.
• Pilot-operated construction: The valve works from zero pressure differential and uses resilient soft seating for tight shutoff.
• Lightweight aluminum body: Trim and internal parts are steel and stainless steel, and the seals are NBR.
• High flow capacity: Designed for low-pressure fuel gas, city gas and air service.
• NPT threaded connections: They fit standard gas piping.
• Agency approvals: The Series 8215 line carries UL, CSA, CE and FM approvals, which vary by model.

These valves suit industrial burners, commercial boilers, heating equipment and combustion systems. They are also used in other fuel gas shutoff applications that need reliable, code-compliant control. Check each variant for its size, flow capacity, BTU rating and voltage.
