ASCO 8220G401-240V Solenoid Valve

The ASCO 8220G401-240V is a high-performance 2-way normally closed solenoid valve designed specifically for demanding steam and hot water applications. Engineered with a rugged brass body and a durable EPDM diaphragm, this pilot-operated solenoid valve provides a reliable solution for industrial systems, including laundries, autoclaves, and boiler controls. With a 3/8" NPT connection and a 4.4 Cv flow coefficient, it delivers up to 60% more flow than many competitive models. This ASCO RedHat valve is built to handle internal pressures from 5 to 50 PSI for steam and 5 to 150 PSI for hot water, ensuring consistent performance in high-temperature environments up to 300°F. The NEMA 4X enclosure provides superior protection against corrosion and environmental elements, making it an ideal choice for both indoor and outdoor HVACR installations requiring a 240Vac power supply. Its floating diaphragm design minimizes wear, significantly extending the service life of the internal components in rapid-cycle operations.

• Versatile Dual-Service: Engineered to manage both steam and hot water, reducing the need for multiple valve types in your inventory.
• Superior Flow Capacity: Features a high 4.4 Cv rating, providing efficient fluid handling and improved system throughput.
• Enhanced Durability: The floating EPDM/PTFE diaphragm design is tested for up to 1 million cycles on hot water and low-pressure steam.
• Rugged Protection: Standard NEMA 4X watertight and corrosion-resistant enclosure ensures longevity in harsh industrial conditions.
• Serviceability: Threaded bonnet design allows for quick inspection and internal maintenance, minimizing system downtime.

What is the maximum temperature rating for the ASCO 8220G401-240V?
This valve is rated for temperatures up to 300°F (149°C) for steam applications and 210°F (99°C) for hot water service.

Does this valve require a minimum pressure differential to operate?
Yes, as a pilot-operated valve, it generally requires a minimum differential of 5 PSI to ensure the diaphragm opens and closes correctly.

Can I use this solenoid valve in outdoor environments?
Yes, the NEMA 4X enclosure is designed to protect against windblown dust, rain, and corrosion, making it suitable for outdoor use.
