ASCO 8210G3-480V Solenoid Valve

The ASCO 8210G3-480V Solenoid Valve is a high-performance, 2-way normally closed pilot-operated valve engineered for reliable fluid control in demanding industrial and HVACR environments. Built with a rugged brass body and durable NBR seals, this 3/4" NPT solenoid valve is designed for general service applications involving air, water, and light oil. Operating on a 480Vac electrical supply, it features a 6.5 Cv flow factor, ensuring efficient high-flow performance. This pilot operated solenoid valve supports a broad pressure range, including 5-250 PSI for air, 5-150 PSI for water, and 5-100 PSI for light oil. The integrated NEMA 4X enclosure provides superior protection against corrosion and water ingress, making it an ideal ASCO RedHat valve for car washes, laundry equipment, and industrial water control systems. With its robust internal construction and 480V AC coil, this valve delivers the precision and longevity required for critical process automation.

• Versatile Media Compatibility: Effectively manages air, inert gas, water, and light oil (up to 300 SSU).
• Superior Protection: Equipped with a NEMA 4X watertight enclosure to endure harsh washdown or outdoor environments.
• High Flow Efficiency: A 6.5 Cv rating allows for significant volume throughput in 3/4" piping systems.
• Reliable Operation: The pilot-operated design ensures consistent opening and closing even in high-pressure cycles.
• Flexible Installation: Can be mounted in any position, though upright mounting is recommended to minimize sediment buildup.

How do I troubleshoot an ASCO 8210G3 valve that won't open?
First, verify that the 480Vac power supply is reaching the coil and that the voltage is at least 85% of the nameplate rating. Check for a "metallic click" when energized; the absence of this sound may indicate a burned-out coil or electrical fault. Ensure the system pressure meets the minimum 5 PSI requirement for pilot-operated valves.

Can this valve be used for steam or hot water applications?
While the brass body and NBR seals are excellent for general service up to 180°F, specific "HW" suffix models are recommended for dedicated hot water service. For steam, a different elastomer or 8222 series valve is typically required.

Is maintenance possible without removing the valve from the line?
Yes, the ASCO 8210G3 is designed for easy "in-line" servicing. You can replace the coil or install a rebuild kit containing a new core and diaphragm assembly without disturbing the pipe connections.
