ASCO 8221G5HW Valve
The ASCO 8221G5HW Valve is a high-performance 2-way normally closed solenoid valve engineered specifically for demanding hot water applications. Utilizing a robust brass body and reliable NBR seals, this pilot operated solenoid valve manages flow pressures ranging from 5 to 150 PSI. The 120Vac coil powers a slow closing valve mechanism designed to mitigate water hammer, protecting your HVACR infrastructure from damaging pressure spikes. With a 3/4" NPT connection and a 5.5 Cv flow coefficient, it serves as a critical component for industrial temperature control and fluid management. The NEMA 4X enclosure provides superior protection against corrosion and environmental ingress, making it ideal for institutional and commercial plumbing systems where durability is paramount. Integrating this ASCO hot water valve ensures precise fluid regulation while maintaining system integrity in high-cycle environments.
Key Benefits- Anti-Water Hammer Design: The slow closing feature prevents pipe vibration and mechanical stress.
- High Temperature Resilience: Specialized internal components optimized for hot water solenoid valve applications.
- Weatherproof Protection: Features a NEMA 4X rated enclosure for watertight and corrosion-resistant performance.
- Reliable Flow Control: High 5.5 Cv rating ensures efficient throughput for 3/4 inch plumbing lines.
How does a slow-closing solenoid valve prevent water hammer?
The ASCO 8221 series utilizes a pilot-operated diaphragm that closes at a controlled rate, gradually stopping the flow of water to prevent the kinetic energy from creating a shockwave in the pipes.
Is the 8221G5HW compatible with high-pressure steam?
No, this specific model is optimized for hot water service up to 150 PSI. For steam applications, a valve with EPDM or Teflon seals and a different pressure rating is required.
Can this valve be mounted in any orientation?
For optimal performance and to reduce the risk of sediment buildup, it is recommended to mount the valve with the solenoid vertical and upright.
