Overview
ASCO 8210G100DC24/DCD is a 2-way, normally closed solenoid valve from the economical ASCO Series 210 line. Manufactured by ASCO (Emerson Industrial Automation), this solenoid valve combines robust brass construction with high-flow capability for liquid, corrosive, air, and inert gas service. The valve features a 1-inch (1-3/4″) orifice with 43 Cv rating, 2-inch female NPT connections, 24 VDC coil at 11.6 W, and 18-inch leads for plug-and-play integration into existing fluid control systems.
Key Features
- Normally Closed Direct-Acting Design: Valve remains closed when de-energized; opens on 24 VDC coil energization for safe, predictable operation.
- Brass Body with Buna-N Seals: Corrosion-resistant forged brass construction rated for indoor and outdoor installations with NBR elastomer seals.
- High Flow Capacity: 43 Cv factor enables efficient media transfer at full operating pressure without excessive pressure drop.
- Red Hat II Enclosure: NEMA 1, 2, 3, 3S, 4, and 4X rated enclosure options provide environmental protection in wet, corrosive, and hazardous locations.
- Wide Pressure & Media Range: Rated for air/inert gas 5–150 PSI, water 5–125 PSI, and light oil 5–90 PSI operation up to 150°F fluid temperature.
