ASCO 8220G9 Solenoid Valve

The ASCO 8220G9 Solenoid Valve is a high-performance 2-way normally closed valve engineered specifically for demanding hot water and steam applications. Featuring a rugged brass body and high-grade EPDM diaphragm, this 1-1/4 inch NPT solenoid valve provides exceptional durability in high-temperature environments. Operating on a reliable 120V/60Hz AC power supply, it utilizes a pilot-operated mechanism to manage substantial flow rates with a 15 Cv flow coefficient. This valve is designed to handle 5-50 PSI for steam and 5-150 PSI for hot water, ensuring precise fluid control in industrial boiler systems and HVACR installations. The integration of a NEMA 4X enclosure offers superior protection against corrosion and moisture, making it an ideal choice for industrial solenoid valve replacements where reliability is paramount. Its robust internal construction is optimized for longevity and consistent cycling in commercial plumbing and thermal management systems.

Key Benefits:

• High Flow Capacity: The 15 Cv rating ensures efficient fluid movement in 1-1/4" piping systems.
• Specialized Sealing: Equipped with an EPDM diaphragm for superior resistance to steam and hot water degradation.
• Extreme Durability: NEMA 4X rated enclosure provides watertight and corrosion-resistant protection for electrical components.
• Versatile Pressure Range: Effectively handles variable pressure differentials common in steam and hydronic heating loops.
• Precision Engineering: ASCO’s pilot-operated design ensures reliable opening and closing cycles under high-demand conditions.

Common Questions:

How does the ASCO 8220G9 handle high-temperature steam?
This valve is specifically designed with EPDM elastomers and a brass body to withstand the thermal stresses of steam applications up to 50 PSI.

Can the ASCO 8220G9 be used in outdoor environments?
Yes, the NEMA 4X enclosure provides the necessary protection against windblown dust, rain, and corrosion for outdoor or wash-down installations.

What is the minimum pressure required for this valve to operate?
As a pilot-operated valve, it requires a minimum differential pressure of 5 PSI to ensure the diaphragm lifts and closes correctly.
