ASCO 8221G11-240V Solenoid Valve

The ASCO 8221G11-240V Solenoid Valve is a high-performance, 2-way normally closed electrical component designed for precise fluid control in industrial and HVACR systems. This pilot operated solenoid valve features a 1.5-inch NPT connection and is specifically engineered for water service applications requiring a slow closing mechanism. By utilizing an internal snubber to decelerate the disc closing speed, this valve effectively eliminates water hammer and protects downstream piping from damaging pressure spikes. Constructed with a rugged brass body and durable NBR seals, it maintains a high flow coefficient of 24 Cv while operating within a pressure range of 5 to 150 PSI. The unit is powered by a 240Vac supply and protected by a NEMA 4 enclosure, ensuring reliable performance in demanding environments where dust and water protection are essential.

Key Benefits:

• Water Hammer Prevention: The integrated slow closing design mitigates shock and system noise.
• High Flow Efficiency: Features a generous 24 Cv rating for high-volume water management.
• Industrial Durability: Equipped with a NEMA 4 enclosure for superior environmental protection.
• Robust Materials: Built with a brass body and NBR seals for long-term reliability in water systems.
• Reliable Scaling: Designed for an operating pressure range of 5-150 PSI.

Common Questions:

How does a slow-closing solenoid valve prevent water hammer?
The ASCO 8221G11 uses a pilot-operated snubber that slows the disc's movement during shut-off, preventing the sudden stoppage of fluid that causes kinetic energy to turn into destructive pressure waves.

Is the ASCO 8221G11-240V suitable for potable water?
This specific model is typically intended for industrial clear water service; please verify local lead-free compliance requirements if considering for drinking water applications.

Can this valve be mounted in any orientation?
For optimal performance and to reduce the risk of sediment buildup in the pilot orifice, it is highly recommended to mount the valve with the solenoid in an upright, vertical position.
