ASCO 8210G9-12VDC Solenoid Valve

The ASCO 8210G9-12VDC Solenoid Valve is a pilot-operated, 2-way normally closed general service valve engineered for high-flow applications in commercial and industrial systems. Built with a durable brass body and NBR (Nitrile) seals, this 3/4" NPT valve is optimized for 12V DC operation, providing reliable fluid control for air, inert gas, water, and light oil. As part of the ASCO RedHat II series, it includes a NEMA 4X enclosure, ensuring watertight and corrosion-resistant protection for rigorous environments like car washes, laundry equipment, and industrial water control systems.

This pilot-operated solenoid valve delivers a 5.0 Cv flow coefficient, maintaining performance across varied pressure differentials: 5-100 PSI for air, 5-90 PSI for water, and 5-75 PSI for light oil. The normally closed configuration ensures the valve remains in a fail-safe shut position until the 11.6-watt DC coil is energized. Designed for general service duty, it handles media temperatures up to 150°F, making it a staple for contractors requiring a high-reliability 3/4 inch solenoid valve for 12V DC pneumatic or hydraulic circuits.

Key Benefits:

• High-Flow Capacity: The 5.0 Cv rating and 3/4" orifice support moderate to high flow rates with minimal pressure drop.
• Rugged Construction: Brass body and NBR seals offer long-term compatibility with non-corrosive fluids.
• Environmental Protection: Standard NEMA 4X enclosure provides superior resistance to dust, rain, and hose-directed water.
• Reliable DC Actuation: Optimized for 12V DC systems, drawing 11.6 watts for stable, consistent switching.
• Versatile Media Handling: Suitable for air, inert gas, water, and light oil up to 300 SSU.

Common Questions:

Can the ASCO 8210G9 be mounted in any orientation?
For optimal performance and to prevent sediment buildup in the pilot-operated mechanism, it is best practice to mount the valve with the solenoid vertical and upright. However, it can be mounted in other positions if necessary for specific piping layouts.

What is the minimum pressure required for this valve to open?
Since this is a pilot-operated solenoid valve, it requires a minimum operating pressure differential of 5 PSI to lift the diaphragm and allow flow. It is not suitable for gravity-fed systems with zero head pressure.

Are rebuild kits available for the 8210G9-12VDC?
Yes, ASCO offers standard spare parts kits containing replacement NBR diaphragms and seals to extend the service life of the valve assembly without replacing the entire brass body.
