Description
ASCO 8210G74 2-Way Normally Closed Solenoid Gas Shutoff Valve
The ASCO 8210G74 is a heavy-duty, pilot-operated solenoid valve engineered for reliable gas shutoff in demanding HVAC and commercial heating applications. Rated at 2.8 Cv with a capacity of up to 150,000 BTU/hr, this valve delivers the flow performance needed for high-capacity gas systems. The normally closed design ensures the valve defaults to a safe, closed position whenever power is removed — a critical safety feature for gas control applications.
Key Features
- 2-Way, Normally Closed (NC) configuration for fail-safe gas shutoff
- 3/8″ NPT pipe connection for straightforward installation
- 120VAC coil voltage for compatibility with standard commercial power supplies
- 2.8 Cv flow coefficient — rated up to 150,000 BTU/hr gas capacity
- Operating pressure range: 0–50 PSI
- Pilot-operated design for efficient, low-power actuation
- Brass body construction for corrosion resistance and long service life
- NBR (Buna-N) seals for compatibility with natural gas and LP gas media
- NEMA 4X enclosure rating — suitable for indoor and outdoor use, including wet and corrosive environments
Application
The ASCO 8210G74 is ideal for use as a gas shutoff valve in commercial HVAC systems, boilers, furnaces, rooftop units, and other gas-fired equipment. Its NEMA 4X-rated enclosure makes it well suited for installations where moisture, dust, or corrosive atmospheres are a concern. The pilot-operated mechanism ensures reliable, consistent operation across the full rated pressure range.
