ASCO 8220G7 Solenoid Valve

The ASCO 8220G7 Solenoid Valve is a 2-way normally closed, pilot-operated valve engineered specifically for high-demand steam and hot water applications. Built with a rugged brass body and high-grade EPDM diaphragm, this 1" NPT valve provides exceptional durability and chemical resistance in thermal systems. With a high flow coefficient of 13.5 Cv, it ensures efficient fluid management across a pressure range of 5-50 PSI for steam and 5-150 PSI for hot water. The 120V AC coil is protected by a NEMA 4X enclosure, making it suitable for washdown environments and corrosive industrial settings. Whether managing boiler feed water or process steam control, the 8220G7 delivers the ASCO RedHat reliability required for critical HVACR and industrial automation infrastructure.

Key Benefits

• High Temperature Resistance: The EPDM diaphragm is designed to withstand the rigorous demands of continuous hot water and steam service.
• Reliable Zero-Leakage Shutoff: The normally closed operation ensures the valve remains securely sealed when de-energized to prevent fluid loss.
• Superior Protection: A NEMA 4X enclosure provides watertight and dust-tight protection, extending the service life of the 120V AC solenoid.
• Optimized Flow Performance: The 13.5 Cv rating allows for high-capacity throughput in 1-inch piping systems.

Common Questions

What is the maximum temperature rating for the ASCO 8220G7?
This steam solenoid valve is typically rated for temperatures up to 300°F, provided the pressure remains within the 5-50 PSI range for steam applications.

Does this valve require a minimum pressure to operate?
Yes, as a pilot-operated valve, it requires a minimum differential pressure of 5 PSI to open the main orifice and ensure stable operation.

Can the 8220G7 be mounted in any orientation?
For optimal performance and to prevent sediment buildup in the solenoid base, it is recommended to mount the valve with the solenoid vertical and upright.
