ASCO 8220G25-24V Solenoid Valve

The ASCO 8220G25-24V Solenoid Valve is a high-performance 2-way normally closed pilot operated valve engineered specifically for demanding steam and hot water applications. Designed with a rugged brass body and durable EPDM diaphragm, this 1 inch NPT solenoid valve ensures reliable fluid control in industrial HVACR systems. It features a high 13.5 Cv flow coefficient, supporting pressure ranges from 5 to 125 PSI for steam and up to 150 PSI for hot water. Operating on a 24Vac power supply, this unit is housed in a robust NEMA 4X enclosure, providing superior protection against corrosion and harsh environmental conditions. Whether integrated into boiler systems or commercial laundry equipment, the ASCO RedHat series 8220G25 gas and liquid valve delivers precision and longevity. This pilot operated brass solenoid valve is the industry standard for professionals seeking efficient thermal energy management and fluid automation solutions.

Key Benefits

• High Thermal Resilience: Specially formulated EPDM seals withstand high-temperature steam and hot water cycles.
• Superior Flow Rate: A 13.5 Cv rating allows for high-volume fluid transfer through 1-inch NPT piping.
• Environmentally Protected: The NEMA 4X rated watertight enclosure prevents ingress in washdown or corrosive environments.
• Reliable Pilot Operation: Minimum differential pressure ensures consistent opening and closing under high-pressure loads.

Common Questions

What is the minimum pressure required for the ASCO 8220G25 to operate?
This pilot-operated valve requires a minimum pressure differential of 5 PSI to function correctly and ensure the diaphragm lifts.

Can this 24Vac solenoid valve be used for cold water applications?
While optimized for steam and hot water, the brass construction and EPDM seals are compatible with cold water, provided there is no risk of freezing.

Is the coil on the 8220G25-24V replaceable?
Yes, ASCO RedHat valves feature interchangeable coils, allowing for easy maintenance or voltage adjustments without removing the valve body from the line.
