ASCO 8221G11-480V Solenoid Valve

The ASCO 8221G11-480V Solenoid Valve is a high-performance 2-way normally closed solenoid valve engineered for precision water service applications in commercial and industrial HVACR systems. This pilot operated slow closing valve is specifically designed to reduce water hammer, protecting your piping infrastructure from pressure surges. Featuring a robust brass body and high-quality NBR seals, it provides a reliable seal and long-lasting performance. With a 1 1/2 inch NPT connection and a high flow coefficient of 24 Cv, this valve efficiently manages high-volume flow under pressures ranging from 5 to 150 PSI. Operating on a 480Vac electrical supply, the unit is encased in a NEMA 4 enclosure, ensuring watertight protection for internal components in demanding environments. This ASCO RedHat valve is the industry standard for reliable fluid control and automated water distribution systems.

• Water Hammer Mitigation: The slow closing solenoid valve design prevents damaging pressure spikes in plumbing systems.
• High Flow Capacity: A 24 Cv flow rating allows for efficient movement of large volumes of water.
• Industrial Durability: The NEMA 4 enclosure provides superior protection against water ingress and environmental debris.
• Reliable Sealing: Equipped with NBR seals to ensure leak-free operation in standard water applications.

Common Questions

How does this valve prevent water hammer?
The ASCO 8221G11 utilizes a pilot-operated diaphragm with a controlled closing speed, which gradually stops the flow of water to eliminate the kinetic shock known as water hammer.

Can this valve be used for high-voltage industrial systems?
Yes, this specific model is designed for 480V solenoid valve applications, making it ideal for heavy-duty industrial electrical grids.

Is the NEMA 4 rating suitable for outdoor use?
The NEMA 4 enclosure is designed to protect against windblown dust and rain, splashing water, and hose-directed water, making it suitable for many outdoor and wash-down environments.
