ASCO 8210G94-120VDC Solenoid Valve

The ASCO 8210G94-120VDC Solenoid Valve is a rugged, 2-way normally closed pilot-operated valve designed for high-performance fluid control in demanding HVACR and industrial environments. Featuring a forged brass body and NBR (Buna-N) seals, this 1/2-inch NPT valve is engineered to handle air and water media with a flow coefficient (Cv) of 4. The 120V DC solenoid operator ensures reliable actuation in specialized electrical circuits, while the NEMA 4X enclosure provides superior protection against corrosion and moisture in washdown or outdoor installations.

This ASCO Series 210 (8210) model operates within a pressure range of 0 to 40 PSI, making it ideal for low-pressure general service applications where zero differential capability or high flow rates are required. Its internal pilot-operated design minimizes power consumption while maintaining a tight shut-off. For long-term reliability, technicians should ensure the valve is mounted in a vertical and upright position to prevent sediment accumulation in the core tube area, particularly when used in potable water or pneumatic systems.

Key Benefits

• High Flow Capacity: Optimized 4 Cv flow factor allows for significant volume handling through 1/2-inch NPT piping.
• NEMA 4X Protection: Includes a watertight and corrosion-resistant Solenoid Enclosure suitable for harsh industrial sites.
• Rugged Construction: Built with a brass body and stainless steel internal components to resist mechanical wear.
• Zero Minimum Pressure: Advanced pilot-operated design functions effectively even at 0 PSI differential.
• Broad Compatibility: Standard NBR seals provide excellent compatibility with air, inert gas, and water up to 180°F.

Common Questions

What is the minimum pressure required for this valve to open?
Unlike some pilot-operated valves that require a delta-P, the 8210G94 is designed to operate from 0 PSI up to its maximum rating of 40 PSI.

Can I use an AC coil with this specific valve body?
While the 8210 series offers AC configurations, this specific unit is factory-spec'd for 120VDC. Swapping coils between AC and DC often requires different internal solenoid base sub-assemblies due to magnetic flux differences.

Is the NEMA 4X enclosure suitable for outdoor use?
Yes, the NEMA 4X rating indicates protection against windblown dust, rain, and hose-directed water, making it a standard choice for corrosive environments.
