ASCO 8220G410 Solenoid Valve

The ASCO 8220G410 Solenoid Valve is a high-performance, 2-way normally closed pilot operated brass body valve specifically engineered for demanding steam and hot water service. This 1-inch NPT valve features a robust EPDM diaphragm and a high flow coefficient of 11.5 Cv, ensuring efficient fluid control in industrial applications. Designed to handle pressures from 5-50 PSI for steam and up to 150 PSI for hot water, it utilizes a 120Vac power supply. The NEMA 4X enclosure provides superior protection against corrosion and water ingress, making it ideal for harsh environments like laundries, autoclaves, and boiler systems. With a floating PTFE diaphragm design, this ASCO RedHat series valve delivers exceptional durability and a long cycle life, significantly reducing maintenance downtime. Its 120V AC coil is built for reliable actuation, providing a "fail-safe" normally closed position to prevent unintended flow during power loss.

• Dual-Service Versatility: Optimized for both high-temperature steam (up to 300°F) and hot water (up to 210°F) applications.
• Enhanced Durability: Features a floating PTFE diaphragm and stainless steel internal parts for a longer operational lifespan.
• Rugged Construction: The forged brass body and NEMA 4X watertight enclosure ensure reliable performance in washdown or corrosive environments.
• High Flow Capacity: The 11.5 Cv rating allows for maximum throughput, outperforming many competitors in the 1-inch pipe class.
• Simplified Serviceability: Designed with a threaded bonnet for quick internal inspection and easy diaphragm replacement.

What is the minimum pressure required for the ASCO 8220G410 to operate?
As a pilot-operated valve, it requires a minimum differential pressure of 5 PSI to open and function correctly. It is not suitable for zero-pressure or gravity-fed systems.

Can this valve be used for potable water?
No, this specific brass model is restricted from use in systems conveying water for human consumption; it is strictly for industrial steam and hot water service.

Why is my solenoid valve humming or buzzing?
A slight hum is normal for AC-powered solenoids. However, loud buzzing or "chattering" often indicates debris trapped in the core tube or a damaged shading coil, which requires cleaning or part replacement.
