ASCO 8220G91 Solenoid Valve

The ASCO 8220G91 Solenoid Valve is a high-performance 2-way normally open solenoid valve designed for demanding HVACR and industrial fluid control applications. Engineered with a durable brass body and high-grade EPDM diaphragm, this 3/8" NPT solenoid valve excels in managing high-temperature media, offering a 3 Cv flow capacity. Operating on 120Vac, the pilot-operated mechanism ensures reliable performance for steam and hot water applications, handling up to 125 PSI for steam and 150 PSI for hot water. The rugged NEMA 4X enclosure provides superior protection against corrosion and environmental elements, making it an ideal choice for industrial steam control systems. By utilizing ASCO RedHat technology, this valve minimizes downtime and optimizes energy efficiency within your piping infrastructure. Whether you are searching for a high-temperature solenoid valve or an ASCO 8220 series replacement, the 8220G91 delivers precision and longevity in the most rigorous thermal environments.

Key Benefits

• High Thermal Tolerance: Specifically designed to handle steam up to 125 PSI and hot water up to 150 PSI.
• Superior Environmental Protection: The watertight NEMA 4X enclosure ensures operation in washdown or corrosive environments.
• Optimized Flow Performance: A 3 Cv flow coefficient provides efficient fluid movement for 3/8" piping systems.
• Durable Construction: Features a rugged brass body and EPDM elastomers for extended service life in hot glass or boiler applications.
• Reliable Normally Open Logic: Ensures the valve remains open during power loss, critical for specific safety and process requirements.

Common Questions

What is the maximum operating temperature for the ASCO 8220G91?
This valve is designed for high-temperature service, typically rated for steam and hot water applications reaching up to 300°F to 350°F depending on the specific pressure configuration.

Can this valve be mounted in any orientation?
For optimal performance and to prevent debris accumulation, it is recommended to mount the valve with the solenoid vertical and upright, though ASCO pilot-operated valves are versatile in many installations.

Is the EPDM diaphragm compatible with oil-based fluids?
No, EPDM seals are ideal for hot water and steam but should not be used with petroleum-based oils or lubricants. For oil applications, a Viton or FKM option is required.
