ASCO 8220G409 Solenoid Valve

The ASCO 8220G409 is a premium 2-way normally closed solenoid valve specifically engineered for high-performance control in steam and hot water applications. This pilot operated solenoid valve features a robust brass body and a 3/4" NPT connection, ensuring reliable fluid handling in demanding commercial and industrial environments. With an impressive 8.8 Cv flow coefficient, it manages pressure ratings up to 125 PSI for steam and 150 PSI for hot water. The integration of a NEMA 4X enclosure provides superior protection against corrosion and moisture, making it ideal for washdown environments or outdoor installations. Utilizing an EPDM diaphragm, the 8220G409 ensures tight shut-off and long-cycle life. Its threaded bonnet design allows for rapid internal access, significantly reducing maintenance downtime for HVAC and boiler feed systems.

Key Benefits of the ASCO 8220G409

• Environmentally Rugged: The watertight NEMA 4X rating ensures longevity in harsh, corrosive, or outdoor settings.
• Efficient Flow Control: A high 8.8 Cv rating allows for maximum flow with minimal pressure drop.
• Simplified Maintenance: The threaded bonnet design enables quick servicing without removing the valve from the piping.
• Versatile Compatibility: Standard 120V AC coil and 3/4 inch NPT ports fit most standard industrial configurations.

Common Questions

What is the maximum temperature rating for this valve?
The ASCO 8220G409 is designed for high-temperature service, typically rated for steam up to 353°F and hot water up to 210°F, depending on specific operating pressures.

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 ensure the diaphragm opens and closes correctly.

Can this solenoid valve be mounted in any orientation?
While ASCO valves are versatile, it is highly recommended to mount the 8220G409 with the solenoid vertical and upright to prevent sediment buildup in the core tube area.
