Description
Overview
The ASCO 8210G56 is a general-service, pilot-operated solenoid valve engineered for reliable fluid control across a wide range of HVAC, industrial, and commercial applications. Featuring a 2-way, normally closed configuration, this valve remains closed when de-energized and opens upon application of 120VAC power — providing fail-safe shutoff for air, water, and light oil systems.
Key Features
- 2-Way, Normally Closed (NC) operation — closes automatically when power is removed
- 1-1/2″ NPT pipe connection for straightforward installation into standard piping systems
- 120VAC coil voltage for compatibility with common control circuits
- High flow capacity with a 22.5 Cv flow coefficient
- Pilot-operated design for efficient actuation at higher pressures
- Brass body construction for durability and corrosion resistance
- NBR (Buna-N) seals suitable for air, water, and light oil media
- NEMA 4X enclosure rating — provides protection against dust, splashing water, and corrosion for indoor and outdoor use
