ASCO 8220G31 Solenoid Valve

The ASCO 8220G31 Solenoid Valve is a high-performance 2-way normally closed pilot-operated valve engineered for demanding high-temperature applications. Featuring a robust brass body and a 2-inch NPT connection, this 120V AC solenoid valve is optimized for controlling the flow of steam and hot water in industrial HVACR systems. It boasts a high flow coefficient of 43 Cv, supporting pressure ranges of 5-125 PSI for steam and 5-150 PSI for hot water. The integration of an EPDM diaphragm ensures excellent thermal resistance and durability, while the NEMA 4X enclosure provides superior protection against corrosion and environmental elements. Designed for precision and reliability, this industrial steam valve is a critical component for maintaining efficient thermal management and fluid control in complex mechanical environments.

Key Benefits

• High Flow Efficiency: A 43 Cv rating ensures maximum throughput with minimal pressure drop across large-scale piping systems.
• Robust Environmental Protection: The NEMA 4X rated enclosure allows for safe installation in washdown or corrosive environments.
• Specialized Sealing: High-grade EPDM elastomers are specifically chosen for long-term resilience in hot water and steam service.
• Reliable Operation: The pilot-operated floating diaphragm design allows for consistent opening and closing even at high pressures.

Common Questions

What is the maximum temperature rating for the ASCO 8220G31?
This valve is designed to handle steam up to 125 PSI and hot water up to 150 PSI, typically rated for temperatures reaching 353°F depending on the specific fluid media.

Does this valve require a minimum pressure differential?
Yes, as a pilot-operated valve, the 8220G31 requires a minimum differential of 5 PSI to ensure the internal diaphragm lifts and seats correctly.

Can the NEMA 4X enclosure be used outdoors?
Yes, the NEMA 4X rating indicates the housing is watertight and dust-tight, providing excellent protection against windblown dust, rain, and hose-directed water.
