ASCO 8220G407-240V Solenoid Valve

The ASCO 8220G407-240V Solenoid Valve is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding steam and hot water service. This pilot operated brass body valve features a 3/4" NPT connection and an 8.8 Cv flow coefficient, ensuring efficient fluid management in industrial applications. Designed for versatility, it supports 5-50 PSI for steam and 5-150 PSI for hot water, utilizing a durable EPDM diaphragm and a specialized piston construction to withstand temperatures up to 210°F for water and 300°F for steam. The rugged NEMA 4X enclosure provides superior protection against corrosion and water ingress, making it ideal for harsh environments. Powered by a 240Vac coil, this RedHat series valve delivers reliable, long-cycle performance in laundries, autoclaves, and boiler systems. Whether managing heat transfer fluids or process water, the 8220G407 ensures precise control and minimal maintenance downtime for professional HVACR and plumbing installations.

• High Flow Capacity: An 8.8 Cv rating allows for significant volume throughput in 3/4-inch piping systems.
• Extreme Durability: The brass body and EPDM/PTFE seals are built to handle over 1 million cycles on hot water.
• Dual-Media Versatility: A single valve solution for both low-pressure steam and hot water applications.
• Weatherproof Reliability: The watertight NEMA 4X enclosure protects electrical components in washdown or outdoor environments.
• Serviceability: A threaded bonnet design enables quick inspection and internal cleaning without removing the valve from the line.

Is the ASCO 8220G407 compatible with 240V AC power?
Yes, this specific model is designed to operate on 240Vac 60Hz (or 220Vac 50Hz) power supplies commonly found in industrial and commercial settings.

What is the maximum pressure rating for steam?
This 3/4" NPT steam valve is rated for a maximum operating pressure differential of 50 PSI for steam and 150 PSI for hot water service.

Can this valve be used for chemical applications?
While the EPDM diaphragm and brass body are excellent for water and steam, always check chemical compatibility charts for specific corrosive media before installation.
