ASCO 8221G1 Valve
The ASCO 8221G1 is a high-performance 2-way normally closed solenoid valve specifically engineered for water service applications requiring precision control. This 3/8" NPT water solenoid valve features a pilot operated diaphragm design with a specialized slow closing mechanism, which effectively eliminates the damaging effects of water hammer in pressurized piping systems. Constructed with a rugged brass body and durable NBR seals, it provides reliable 120Vac operation across a pressure range of 5-150 PSI. With a 3 Cv flow factor and a NEMA 4 enclosure, this assembly is built for demanding environments, ensuring watertight and dust-tight protection for internal components. Whether integrated into industrial cooling systems or commercial irrigation, the ASCO 8210 series evolution found in this model delivers consistent flow management and longevity.
Key Benefits- Anti-Water Hammer Design: The slow-closing feature protects your plumbing infrastructure by reducing pressure spikes.
- Industrial Durability: Robust brass construction and NBR elastomers provide excellent chemical compatibility with water.
- Environmental Protection: The NEMA 4 rated housing allows for safe operation in washdown or outdoor environments.
- High Flow Efficiency: A 3 Cv rating ensures high-volume throughput for a compact 3/8" footprint.
What prevents water hammer in this valve?
The ASCO 8221G1 utilizes a pilot-operated diaphragm with a controlled closing speed to prevent the shockwaves associated with rapid valve shut-off.
Can this valve be used for air or oil?
This specific model is optimized for water service; using it with other media may affect the slow-closing timing or seal integrity.
Does it require a minimum pressure to operate?
Yes, as a pilot-operated valve, it requires a minimum differential pressure of 5 PSI to function correctly.
