ASCO 8220G404-240V Solenoid Valve

The ASCO 8220G404-240V Solenoid Valve is a high-performance 2-way normally closed control solution engineered specifically for demanding steam and hot water applications. Featuring a 1/2" NPT connection and a robust brass body, this pilot operated solenoid valve is built to thrive in industrial environments like laundries, autoclaves, and boiler systems. It utilizes a high-durability EPDM diaphragm and a floating PTFE design to ensure positive sealing and a long service life, even under high-temperature conditions. Operating at 240Vac, the valve delivers a substantial 4.7 Cv flow coefficient, providing up to 60% more flow capacity than many competitors. The NEMA 4X enclosure offers superior protection against corrosion and harsh weather, while the internal pilot-operated mechanism allows for reliable performance across a 5-50 PSI steam pressure range and 5-150 PSI for hot water. This RedHat series valve is the professional choice for those seeking efficient fluid automation and reduced maintenance downtime.

• High Flow Efficiency: Optimized internal design provides a 4.7 Cv rating, ensuring maximum media throughput for 1/2" piping.
• Extreme Durability: Rugged brass construction and professional-grade EPDM elastomers are designed to withstand up to 1 million cycles in hot water service.
• Environmental Protection: The NEMA 4X enclosure ensures the solenoid remains protected in washdown or corrosive industrial settings.
• Simplified Maintenance: Features a threaded bonnet that can be easily removed for quick inspection, reducing system downtime.
• Versatile Application: Dual-rated for both steam and hot water, allowing for inventory reduction in mixed-media facilities.

Can the ASCO 8220G404 be used for high-pressure steam?
This specific model is designed for pilot-operated steam service up to 50 PSI and hot water service up to 150 PSI. For pressures exceeding these ratings, please consult our technical team for a compatible high-pressure alternative.

What is the benefit of a Normally Closed (NC) configuration?
A normally closed valve remains in the shut position when it is de-energized, acting as a safety fail-safe to prevent fluid flow during power loss or system standby.

Is this valve suitable for outdoor installation?
Yes, the NEMA 4X rating indicates that the assembly is protected against windblown dust, rain, and hose-directed water, making it suitable for both indoor and outdoor industrial environments.
