ASCO 8220G9-208V Solenoid Valve

The ASCO 8220G9-208V is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding steam and hot water applications. Designed with a robust brass body and an EPDM diaphragm, this pilot operated solenoid valve provides reliable flow control in industrial environments. It features a 1 1/4 inch NPT connection and is rated for a 208V/60Hz power supply. With a high flow coefficient of 15 Cv, it efficiently manages 5-50 PSI steam and 5-150 PSI hot water. The inclusion of a NEMA 4X enclosure ensures the unit is watertight and corrosion-resistant, making it ideal for HVACR systems, industrial laundries, and sterilizers. This ASCO RedHat series valve is built to handle the rigorous thermal environments of process heating, offering on/off control with professional-grade durability. Its internal pilot-operated design allows for high-volume capacity, maintaining stable performance even under fluctuating pressure conditions.

Common Questions

What is the maximum fluid temperature for this valve?
The ASCO 8220G9 is rated for steam up to 300°F and hot water up to 210°F, depending on the specific pressure differential.

Does this valve require a minimum pressure to operate?
Yes, as a pilot operated valve, it typically requires a minimum operating pressure differential of 5 PSI to open and function correctly.

Can this solenoid valve be installed in any orientation?
While many ASCO valves offer flexibility, it is highly recommended to install the valve with the solenoid vertical and upright to prevent sediment buildup and ensure optimal performance.
