ASCO 8220G7-24V Solenoid Valve

The ASCO 8220G7-24V is a high-performance 2-way normally closed solenoid valve engineered for demanding HVACR and industrial fluid control applications. Designed with a 1-inch NPT connection and a robust brass body, this pilot operated solenoid valve provides reliable flow control for high-temperature media. It features a high flow capacity with a 13.5 Cv flow coefficient, making it ideal for systems requiring efficient fluid movement. Equipped with an EPDM diaphragm, the valve is purpose-built to handle 5-50 PSI steam and 5-150 PSI hot water service. The unit operates on 24Vac power and is housed in a rugged NEMA 4X enclosure, ensuring superior protection against corrosion and environmental elements in harsh installations. Whether you are replacing an existing ASCO 8220 series valve or integrating a new hot water and steam solenoid into your system, this unit delivers the precision and durability required for professional-grade thermal management.

Key Benefits:

• High Temperature Resilience: Engineered specifically for steam and hot water applications using durable EPDM seals.
• Robust Environmental Protection: The NEMA 4X watertight enclosure provides exceptional resistance to moisture and corrosion.
• Efficient Flow Management: A generous 13.5 Cv rating ensures minimal pressure drop across the 1-inch NPT ports.
• Reliable Pilot Operation: Designed for consistent opening and closing cycles in high-pressure plumbing and HVAC systems.

Common Questions:

Can the ASCO 8220G7-24V be used for low-pressure steam applications?
Yes, this valve is rated for steam pressures ranging from 5 to 50 PSI, making it suitable for a variety of low to medium pressure steam systems.

What is the benefit of the EPDM diaphragm in this ASCO valve?
The EPDM material is specifically chosen for its excellent compatibility with hot water and steam, preventing premature degradation compared to standard nitrile seals.

Is the NEMA 4X rating suitable for outdoor installation?
Yes, the NEMA 4X rating indicates the valve head is protected against windblown dust, rain, and corrosion, making it suitable for both indoor and outdoor environments.
