Description
ASCO 8222G49 2-Way Normally Closed Solenoid Valve Overview
The ASCO 8222G49 is a heavy-duty, pilot-operated solenoid valve engineered for demanding steam and fluid control applications. Featuring a 2-way, normally closed configuration, this valve remains shut when de-energized and opens upon electrical actuation — providing reliable, fail-safe operation in HVAC, industrial, and process systems. The brass body construction paired with Teflon seals ensures excellent corrosion resistance and long service life in steam environments.
Key Features
- 2-Way, Normally Closed (NC) operation — valve closes when power is removed for inherent fail-safe protection
- Pilot-operated design for efficient, low-power actuation across the rated pressure range
- 3/4″ NPT pipe connection for straightforward installation into standard piping systems
- 120VAC coil voltage for compatibility with common commercial and industrial power supplies
- 4.6 Cv flow coefficient for optimized flow capacity in steam and compatible fluid service
- Rated pressure range: 2–125 PSI — suitable for a wide range of steam system pressures
- Brass body construction offers excellent durability and resistance to corrosion
- Teflon (PTFE) seals provide superior chemical resistance and extended seal life in steam service
- NEMA 4X enclosure rating — provides protection against corrosion, dust, and water ingress, suitable for indoor and outdoor use
