ASCO 8220G404-208V Solenoid Valve

The ASCO 8220G404-208V Solenoid Valve is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding steam and hot water service. This pilot-operated valve features a robust brass body and a durable EPDM diaphragm, making it an ideal choice for industrial laundry equipment, autoclaves, and sterilizers. With a 1/2" NPT connection and a 4.7 Cv flow coefficient, it ensures efficient fluid management across a pressure range of 5-50 PSI for steam and 5-150 PSI for hot water. The 208Vac coil is housed in a NEMA 4X enclosure, providing superior protection against corrosion and water ingress in harsh environments. As part of the ASCO RedHat series, this ASCO 8220G404 model is recognized for its reliability and long service life in high-temperature HVACR and process cooling applications.

Key Benefits

• Optimized for High Temperatures: Specifically designed to handle the rigorous demands of steam and hot water without compromising performance.
• Industrial-Grade Construction: The corrosion-resistant brass body and EPDM seals ensure compatibility with a wide range of thermal fluids.
• Reliable NEMA 4X Protection: The watertight and dust-tight enclosure allows for safe installation in wash-down areas or outdoor environments.
• Precision Flow Control: A 4.7 Cv rating provides the high flow capacity needed for rapid cycling and efficient system operation.
• Simplified Maintenance: The pilot-operated diaphragm design allows for easier inspection and part replacement compared to direct-acting alternatives.

Common Questions

What is the maximum pressure rating for this ASCO valve?
The ASCO 8220G404-208V supports a maximum operating pressure differential of 50 PSI for steam applications and up to 150 PSI for hot water service.

Can this valve be used in outdoor HVAC installations?
Yes, the NEMA 4X enclosure provides excellent protection against windblown dust, rain, and hose-directed water, making it suitable for both indoor and outdoor use.

Is a minimum pressure differential required for operation?
Since this is a pilot-operated solenoid valve, it requires a minimum pressure differential of 5 PSI to open and close the diaphragm effectively.
