Asco 8221G5-24V 3/4 Inch Normally Closed Slow Closing Solenoid Valve

The Asco 8221G5-24V is a 2-way normally closed solenoid valve designed specifically for slow closing applications to prevent water hammer damage in fluid control systems. This pilot-operated valve features a 3/4-inch NPT connection and operates on 24VDC power, making it ideal for industrial water systems, HVAC applications, and other fluid control operations.

Key Features:

• 2-way normally closed configuration remains shut until electrically activated
• Slow closing mechanism with snubber to protect against water hammer more effectively than traditional valves
• Operating pressure range of 5-150 PSI with flow coefficient (Cv) of 5.5
• Forged brass body construction with brass or stainless steel internal components for durability
• NBR (Buna-N) elastomer seals for reliable performance
• NEMA 4 rated enclosure provides protection against water and dust
• Internal pilot-operated design for efficient operation
• 3/4-inch NPT threaded connections for easy installation

The Series 8221 valve's unique slow closing design reduces pressure spikes caused by water hammer to a level that eliminates the need for suppressors or additional controls in most water systems. The valve is constructed with high-quality materials including forged brass body and internal parts of brass or stainless steel, ensuring long-lasting performance in demanding applications.
