ASCO 8220G101 Solenoid Valve

The ASCO 8220G101 Solenoid Valve is a high-performance 2-way normally open solenoid valve engineered specifically for the demanding requirements of steam and hot water applications. Featuring a robust 1 1/2" NPT connection and a high-capacity 22.5 Cv flow coefficient, this pilot-operated valve ensures efficient fluid control in industrial environments. The brass body construction is paired with a durable EPDM diaphragm, making it an ideal choice for boiler control systems, commercial laundry equipment, and autoclaves. Designed to operate on 120Vac, it maintains reliable performance under pressures ranging from 5-125 PSI for steam and 5-150 PSI for hot water. The NEMA 4X enclosure provides superior protection against corrosion and environmental elements, ensuring longevity in harsh conditions. This heavy-duty solenoid valve is a critical component for technicians seeking a high-temperature solenoid valve that combines precision with industrial-grade durability for consistent thermal management.

Key Benefits

• Optimized Flow Capacity: The 1 1/2 inch orifice and 22.5 Cv rating provide superior volume control for large-scale HVACR and process heating systems.
• Extreme Temperature Resilience: Engineered to handle the unique thermal stresses of saturated steam and high-temperature water service.
• Reliable Fail-Safe Operation: The normally open configuration ensures the valve remains in the open position during power loss, facilitating system safety.
• Environmental Protection: The NEMA 4X rated housing protects electrical components from moisture, dust, and hosedown cleaning procedures.
• Serviceable Design: Features a rugged brass body and reliable EPDM seals for extended operational life in high-cycle industrial steam environments.

Common Questions

What is the difference between this model and a normally closed valve?
As a normally open valve, the 8220G101 allows fluid to pass when the coil is de-energized and closes only when 120V AC power is applied. This is typically used for safety venting or continuous flow applications.

Can this solenoid valve be used with other fluids?
While optimized for hot water and steam, the EPDM diaphragm and brass construction are compatible with various neutral fluids. However, always verify chemical compatibility with our technical team before use with non-standard media.

Is a minimum pressure differential required for operation?
Yes, as a pilot-operated valve, this unit requires a minimum pressure differential of 5 PSI to properly lift the diaphragm and function correctly.
