ASCO 8221G27 Solenoid Valve

The ASCO 8221G27 Solenoid Valve is a high-performance 2-way normally open solenoid valve engineered for precision water service applications. Featuring a robust brass body and high-flow 1-inch NPT connections, this pilot operated solenoid valve utilizes a slow-closing design to effectively eliminate water hammer, protecting your piping system from pressure surges. Designed for reliability in demanding environments, it operates on a standard 120V AC solenoid and includes a NEMA 4 enclosure for superior protection against dust and water ingress. With an 11.5 Cv flow coefficient and a pressure range of 5 to 150 PSI, the ASCO RedHat valve ensures consistent performance. Reliable NBR seals provide excellent compatibility with water applications, making it an ideal choice for industrial and commercial fluid control. This industrial water valve combines technical durability with the trusted engineering of the ASCO brand to optimize your HVACR or plumbing infrastructure.

• Water Hammer Prevention: The specialized slow-closing mechanism protects system integrity by reducing hydraulic shocks.
• High Flow Capacity: An 11.5 Cv rating ensures efficient fluid movement through 1-inch NPT ports.
• Environmental Protection: The NEMA 4 rated enclosure safeguards internal components in harsh or damp conditions.
• Durable Construction: High-grade brass body and NBR seals offer long-term resilience for water-based media.

Common Questions

How does a slow-closing solenoid valve prevent pipe damage?
The pilot-operated diaphragm is designed to close at a controlled rate, which prevents the sudden cessation of flow that causes destructive water hammer in plumbing systems.

What is the purpose of the NEMA 4 enclosure on this ASCO valve?
The NEMA 4 rating indicates the valve is watertight and dust-tight, making it suitable for outdoor use or washdown environments where moisture protection is vital.

Can the ASCO 8221G27 be used for low-pressure applications?
This valve requires a minimum differential pressure of 5 PSI to operate the pilot-controlled diaphragm effectively, up to a maximum of 150 PSI.
