ASCO 8210G2-240V Solenoid Valve

The ASCO 8210G2-240V Solenoid Valve is an industrial-grade, 2-way normally closed pilot-operated valve engineered for reliable fluid control in high-demand environments. This 1/2 inch NPT solenoid valve features a rugged brass body and NBR seals, making it suitable for general service applications involving air, water, and light oil. Operating at 240Vac, the ASCO RedHat design ensures a high flow capacity with a 4 Cv rating, supporting a wide range of operating pressure differentials: 5-200 PSI for air/inert gas, 5-150 PSI for water, and 5-135 PSI for light oil. Its NEMA 4X enclosure provides superior protection against corrosion and water ingress, essential for demanding HVACR and industrial installations. Designed for maximum performance, this pilot operated solenoid valve requires a minimum pressure differential of 5 PSI to shift the diaphragm, ensuring consistent opening and closing cycles in applications such as car washes, air compressors, and industrial water control systems. Professionals value the 8210 series for its low internal leakage and field-proven reliability.

• High Flow Efficiency: Delivers a 4 Cv flow factor through a 1/2" orifice, optimizing throughput for general service solenoid valve applications.
• Rugged Construction: Built with a forged brass body and stainless steel internal components for durability in high-pressure cycles.
• Versatile Media Handling: Compatible with air, inert gas, water, and light oils up to 300 SSU.
• Environmental Protection: The NEMA 4X watertight enclosure allows for installation in harsh or wash-down environments.
• Field Serviceable: Standard ASCO construction allows for simplified maintenance and coil replacement without removing the valve body from the line.

Common Questions

What is the minimum operating pressure for this valve?
As a pilot-operated unit, the 8210G2 requires a minimum operating pressure differential (MOPD) of 5 PSI to function correctly. It will not open if the inlet and outlet pressures are equalized or if the system pressure is below this threshold.

Can this valve be mounted in any orientation?
For optimal performance and to prevent sediment buildup in the core tube, it is recommended to mount the valve with the solenoid vertical and upright. While it can function in other orientations, this position minimizes wear on the internal springs and plugnut.

What are the temperature limits for the media and ambient environment?
The standard NBR seals and Class F coil are designed for fluid temperatures up to 180°F. The RedHat II solenoid is rated for ambient temperatures ranging from 32°F to 125°F for AC operation.
