ASCO 8220G406-24V Solenoid Valve

The ASCO 8220G406-24V Solenoid Valve is a high-performance, 2-way normally closed pilot-operated valve specifically engineered for demanding steam and hot water applications. Featuring a robust brass body and an EPDM diaphragm, this valve ensures reliable fluid control in industrial environments like laundries, autoclaves, and sterilizers. With a 1/2 inch NPT connection and a flow coefficient of 4.7 Cv, it provides efficient flow management for high-temperature media. The unit operates on a 24Vac power supply and is housed in a NEMA 4X enclosure, offering superior protection against corrosion and environmental elements. Designed for longevity, the ASCO RedHat series delivers consistent performance with a pressure rating of 5 to 125 PSI for steam and up to 150 PSI for hot water. This pilot operated solenoid valve is the ideal choice for technical professionals seeking a durable, low-maintenance solution for thermal system regulation.

• Dual-Media Versatility: Optimized for both high-temperature steam (up to 353°F) and hot water (up to 210°F), reducing the need for multiple valve types.
• Rugged Construction: Built with a corrosion-resistant brass body and a durable NEMA 4X rated enclosure for harsh washdown environments.
• High Flow Capacity: Features a 4.7 Cv flow factor to maintain system efficiency in 1/2" piping configurations.
• Enhanced Reliability: The pilot-operated diaphragm design is tested for up to 1 million cycles on hot water, ensuring long-term operational uptime.

What is the maximum pressure for steam applications?
The ASCO 8220G406-24V is rated for a pressure range of 5 to 125 PSI specifically for steam service.

Does this valve require a minimum differential pressure?
Yes, as a pilot operated valve, it typically requires a minimum pressure differential (5 PSI) to open and remain functional.

Is the coil compatible with outdoor installations?
Yes, the NEMA 4X enclosure provides protection against windblown dust, rain, and hose-directed water, making it suitable for demanding indoor and outdoor setups.
