Description
ASCO 8210G104 General Service Solenoid Valve Overview
The ASCO 8210G104 is a heavy-duty, pilot-operated, 2-way normally open solenoid valve engineered for demanding general service applications. With a 2-1/2″ NPT connection, 120VAC coil, and a high flow coefficient of 45 Cv, this valve delivers exceptional flow capacity for air, water, and light oil systems. The normally open (N.O.) design ensures flow passes freely when the coil is de-energized — an ideal configuration for fail-safe process control requirements.
Key Features
- 2-way, normally open (N.O.) pilot-operated configuration
- 2-1/2″ NPT pipe connection for high-flow installations
- 120VAC coil voltage for standard electrical compatibility
- 45 Cv flow coefficient for high-capacity flow control
- Operating pressure range: 5–125 PSI

Application & Installation
Designed for general service environments, the ASCO 8210G104 is well-suited for HVAC, industrial process control, water treatment, and fluid handling systems. The pilot-operated design leverages line pressure to assist valve actuation, making it highly efficient for larger pipe sizes. The NEMA 4X rated enclosure ensures reliable operation in wet, corrosive, or washdown environments, while the brass body and NBR seals provide long service life across a broad range of compatible media.
