ASCO 8220G401-24V Solenoid Valve

The ASCO 8220G401-24V is a high-performance, 2-way normally closed pilot operated solenoid valve designed for the demanding requirements of steam and hot water control. Featuring a rugged brass body and a durable EPDM diaphragm, this valve is engineered to withstand extreme thermal cycling in industrial environments. It operates with a 24Vac supply and offers a high flow coefficient of 4.4 Cv, ensuring efficient media delivery across its 3/8" NPT connection. The internal pilot-operated design allows for reliable switching with a minimum operating pressure differential of 5 PSI, supporting pressures up to 50 PSI for steam and 150 PSI for hot water. To ensure longevity in harsh conditions, the unit is housed in a NEMA 4X enclosure, providing superior protection against corrosion and water ingress. This ASCO RedHat series valve is an essential component for laundry equipment, autoclaves, and boiler systems where precise fluid regulation is critical.

• Dual-Media Versatility: Optimized for both high-temperature steam (up to 300°F) and hot water (up to 210°F) applications.
• Robust Construction: Forged brass body with stainless steel internal parts for maximum structural integrity.
• Advanced Sealing: Equipped with an EPDM diaphragm and TFE/P elastomers for leak-proof performance and chemical resistance.
• Weatherproof Reliability: NEMA 4X rated enclosure makes it suitable for both indoor and outdoor installations.
• Efficient Flow: 4.4 Cv flow factor provides substantial capacity within a compact 3/8 inch footprint.

What is the minimum pressure required for this valve to operate?
As a pilot-operated valve, the 8220G401-24V requires a minimum operating pressure differential of 5 PSI to open. It will remain open down to approximately 3 PSI differential once actuated.

Can this solenoid valve be mounted in any orientation?
While ASCO valves are highly versatile, it is highly recommended to mount the valve with the solenoid vertical and upright to prevent sediment from collecting in the core tube area, which can lead to premature wear.

Is the 24Vac coil compatible with DC power systems?
No, this specific model is designed for 24Vac 60Hz operation. Using a DC power supply will result in insufficient opening force and potential coil burnout due to inrush current differences.
