ASCO 8221G7HW Valve

ASCO 8221G7HW Valve

The ASCO 8221G7HW is a high-performance 2-way normally closed solenoid valve specifically engineered for high-temperature applications. Optimized for hot water systems, this 1-inch NPT valve features a pilot-operated design with an integral snubber, which provides a slow-closing mechanism to eliminate damaging water hammer. Built with a durable forged brass body and resilient NBR seals, it ensures reliable flow control in demanding environments. Driven by a 120Vac solenoid, this unit delivers a high 11.5 Cv flow factor and operates within a pressure range of 5 to 150 PSI. The NEMA 4X enclosure offers superior protection against corrosion and moisture, making it ideal for both indoor and outdoor utility service. By reducing pressure spikes throughout your piping, the ASCO 8221G7HW simplifies system design by removing the need for additional surge suppressors in most water-based HVAC and industrial configurations.

Key Benefits
  • Anti-Water Hammer Design: The slow-closing pilot technology prevents pipe vibration and protects system integrity.
  • Hot Water Optimization: Specifically rated for hot water service up to 210°F and 150 PSI.
  • Rugged Construction: Features a brass body and NEMA 4X watertight/corrosion-resistant protection.
  • High Flow Capacity: A large 11.5 Cv rating ensures efficient fluid transfer for 1" pipe sizes.
Common Questions

How does this valve prevent water hammer?
The ASCO 8221G7HW utilizes a built-in snubber that regulates the disc's closing speed, effectively absorbing the energy of moving water and preventing sudden pressure spikes.

What is the minimum pressure required for operation?
As a pilot-operated valve, it requires a minimum differential pressure of 5 PSI to open and function correctly.

Can this valve be used in outdoor environments?
Yes, the NEMA 4X enclosure is designed to provide protection against windblown dust, rain, and hose-directed water, as well as corrosion.
