ASCO 8220G97 2-Way Normally Open Solenoid Valve Overview
The ASCO 8220G97 is a heavy-duty, pilot-operated solenoid valve engineered for demanding steam and hot water applications in commercial and industrial HVAC systems. With a robust brass body, EPDM diaphragm, and NEMA 4X-rated enclosure, this valve delivers reliable, long-service performance in wet, corrosive, or washdown environments.
Key Features
- 2-way, normally open (N.O.) configuration — valve opens when de-energized for fail-safe operation
- Pilot-operated design for efficient, low-power actuation across a wide pressure range
- 1″ NPT port connections for straightforward installation in standard piping systems
- High flow capacity with a 13.5 Cv rating to minimize pressure drop
- 120VAC coil voltage for compatibility with common commercial control circuits
- Brass body construction for excellent corrosion resistance and durability
- EPDM diaphragm — ideal for steam, hot water, and other high-temperature media
- NEMA 4X enclosure rating — suitable for indoor and outdoor use, including washdown and corrosive environments
