ASCO 8221G9 Valve
The ASCO 8221G9 is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding industrial HVACR and liquid control applications. Featuring a 1 1/4 inch NPT connection and a robust brass body, this pilot-operated valve is designed with a specialized slow-closing mechanism to effectively eliminate water hammer and protect your piping system from pressure surges. Equipped with durable NBR seals and a NEMA 4 enclosure, it provides reliable service for water, air, and inert gas within a 5-150 PSI operating range. The unit operates on 120Vac and offers a high 13 Cv flow coefficient, ensuring efficient fluid handling in process control and commercial irrigation systems. As a 2-port slow-close valve, it is the ideal solution for practitioners seeking to mitigate noise and mechanical stress in large-diameter pipelines.
Key Benefits- Water Hammer Prevention: The internal snubber slows the disc closing speed, protecting HVAC infrastructure from damaging pressure spikes.
- High Flow Efficiency: A generous 13 Cv rating allows for high-volume fluid transfer with minimal pressure drop.
- Rugged Construction: Built with a forged brass body and NBR (Nitrile) seals for compatibility with a wide range of non-corrosive fluids.
- Weatherproof Protection: The NEMA 4 enclosure ensures the 120V solenoid remains protected against dust, rain, and hose-directed water.
- Normally Closed Safety: Automatically shuts off flow during power loss, providing essential fail-safe security for your system.
How does the slow-close feature benefit my system?
The slow-closing solenoid valve design utilizes an internal orifice to regulate the closing speed, which prevents the sudden "shock" known as water hammer that can burst pipes or damage fittings.
Can the ASCO 8221G9 be used for high-pressure air?
This pilot-operated valve is rated for 5-150 PSI and is compatible with air and inert gases, provided the minimum 5 PSI differential pressure is maintained for operation.
Is the coil replaceable if the voltage needs to be changed?
While this model is configured for 120Vac, ASCO RedHat II valves often feature interchangeable coils; however, we recommend consulting a technician to ensure NEMA 4 integrity is maintained.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
