ASCO 8221G13-240V Solenoid Valve

The ASCO 8221G13-240V Solenoid Valve is a high-performance 2-way normally closed solution engineered for demanding industrial water service. Featuring a robust brass body and 2-inch NPT connections, this pilot-operated solenoid valve is specifically designed for slow closing functionality. By utilizing an internal snubber to decelerate the disc closing speed, it effectively eliminates water hammer damage, protecting your piping system without the need for additional surge suppressors. Operating on 240Vac, this valve provides a high flow capacity with a 36 Cv rating and a versatile operating pressure range of 5-150 PSI. The integration of NBR seals (Buna-N) ensures reliable performance in standard water applications, while the NEMA 4 enclosure provides watertight protection for both indoor and outdoor environments. This ASCO RedHat II series component is the professional choice for commercial laundries, cooling systems, and large-scale HVACR fluid control where system longevity and surge prevention are critical.

• Water Hammer Prevention: The specialized slow-closing design reduces pressure spikes, significantly extending the lifespan of your plumbing and HVAC infrastructure.
• High Flow Performance: A 36 Cv flow coefficient allows for high-volume fluid transfer through 2" NPT ports, meeting the needs of large-scale commercial applications.
• Resilient Construction: The brass body and NEMA 4 watertight enclosure ensure durability in industrial environments and varied weather conditions.
• Pilot Operated Efficiency: Requires a minimum 5 PSI differential to operate, providing reliable normally closed (NC) fail-safe positioning.

What is the primary advantage of a slow-closing solenoid valve?
Standard valves can close abruptly, creating a shockwave known as water hammer. The ASCO 8221G13 uses a snubber to slow this process, protecting pipes, fittings, and sensors from vibration and rupture.

Can this valve be used for hot water applications?
While designed for general water service with NBR seals, compatibility depends on the specific temperature. This model is often utilized in high-temperature laundry and autoclaving systems; please verify your specific fluid temperature requirements before installation.

Is a minimum pressure required for this valve to function?
Yes, as a pilot-operated valve, it requires a minimum pressure differential of 5 PSI to open and typically remains open down to 3 PSI.
