ASCO 8221G5 Valve

The ASCO 8221G5 is a high-performance 2-way normally closed solenoid valve specifically engineered for water applications requiring precise fluid control. This pilot operated solenoid valve features a 3/4" NPT connection and a robust brass body, ensuring long-lasting durability in demanding HVACR environments. Designed with slow closing technology, the 8221G5 effectively minimizes water hammer, protecting your piping system from pressure surges. Operating on 120V/60Hz AC power, this valve provides a reliable 5.5 Cv flow factor and maintains a pressure range of 5 to 150 PSI. The integration of NBR seals ensures excellent chemical compatibility with water, while the NEMA 4 enclosure provides superior protection against dust and moisture ingress, making it an ideal choice for industrial and commercial water service installations.

Key Benefits:

• Slow Closing Design: Specifically engineered to prevent damaging water hammer in high-flow systems.
• NEMA 4 Rated: Watertight enclosure ensures reliable performance in wash-down or outdoor environments.
• High Flow Capacity: Features a 5.5 Cv rating for efficient fluid handling in 3/4 inch piping.
• Rugged Construction: Forged brass body and NBR elastomers provide a resilient seal and structural integrity.

Common Questions:

What is the primary application for the ASCO 8221G5?
This valve is primarily used for automated water service where a slow-closing mechanism is required to prevent pipe vibration and noise caused by sudden shut-off.

Can this valve be used for high-pressure systems?
The ASCO 8221G5 is rated for a maximum operating pressure differential of 150 PSI for water, making it suitable for most standard commercial plumbing and HVAC applications.

Does this valve require a minimum pressure to operate?
Yes, as a pilot operated valve, it requires a minimum pressure differential of 5 PSI to ensure the diaphragm opens and closes correctly.
